Spark streaming app resets kafka offset continuously

Spark streaming app resets kafka offset continuously - apache-spark

I have a spark streaming app that runs on spark cluster with 4 node. A few days ago the app keeps resetting Kafka offset and does not fetch Kafka data anymore while the AUTO OFFSET RESET is set,
this is the log:

resetting Kafka offset repeats forever without even an error.
I did these actions to solve the problem but it did not any help:
reset Kafka offset to earliest or latest
delete consumer group and create new one
I even changed the topic but nothing changed, so I guessed it was from spark cluster, but I can load Kafka data with Pyspark shell on the same cluster
notes:
the app was working OK about 3 years!
recently we had server migration and some of our resources has been decreased
other non-streaming jobs run on spark cluster without any issue
Is there anything that I'm missing?

Can you confirm what was the value set in AUTO OFFSET RESET before the upgrade? Also you can inspect the offset against the consumer group on that particular topic executing the following command.
bin/kafka-consumer-groups — bootstrap-server localhost:9092 — describe — group consumer-group
Also, check for any KAFKA Upgrade w.r.t broker configuration changes recently.
There are edge case scenarios also for this behaviour due to any poison pills or changes in the consumer behaviour. Because, there are many factors when auto.offset.reset property will kicks in efficiently.
One such case from the doc,
There is an edge case that could result in data loss, whereby a message is not redelivered in a retryable exception scenario. This scenario applies to a new consumer group that is yet to have recorded any current offset (or the offset has been deleted).
Two consumer instances, A and B, join a new consumer group.
The consumer instances are configured with auto.offset.reset as latest (i.e. new messages only).
Consumer A consumes a new message from the topic partition.
Consumer A dies before processing of the message has completed. The consumer offsets are not updated to mark the message as consumed.
The consumer group rebalances, and Consumer B is assigned to the topic partition.
As there is no valid offset, and auto.offset.reset is set to latest, the message is not consumed.

It was from my redis server. After migration it became unstable and sometimes it was not working correctly. so I restarted the service and everything worked fine.

Kafka create stream running but not printing the processed output from Kafka Topic in Pyspark

I am using Kafka version 2.0, Spark version is 2.2.0.2.6.4.0-91 , Python version is 2.7.5
I am running this below code and it streams without any error but the count is not printing in the output.
import sys
from pyspark import SparkContext
from pyspark.streaming import StreamingContext
from pyspark.streaming.kafka import KafkaUtils
import os
if __name__ == "__main__":
sc = SparkContext(appName="PythonStreamingKafkaWordCount")
ssc = StreamingContext(sc, 60)
print("spark cotext set")
zkQuorum, topic = 'master.hdp:2181','streamit'
kvs = KafkaUtils.createStream(ssc, zkQuorum, "console-consumer-68081", {topic: 1})
print("connection set")
lines = kvs.map(lambda x: x[1])
counts = lines.flatMap(lambda line: line.split(" ")) \
.map(lambda word: (word, 1)) \
.reduceByKey(lambda a, b: a + b)
counts.pprint()
ssc.start()
ssc.awaitTermination()
My Spark submit Command is
/usr/hdp/current/spark2-client/bin/spark-submit --principal hdfs-ivory#KDCAUTH.COM --keytab /etc/security/keytabs/hdfs.headless.keytab --master yarn --deploy-mode client --packages org.apache.spark:spark-streaming-kafka-0-8_2.11:2.2.0 kstream.py
The last part of my output log shows. It gets stream but doesn't show the desired processed output.

It seems that you are not using a logger but instead, you are print()ing to standard output. In order to log to your log fils, you need to setup a logger. For example, the following gets the logger from SparkContext:

50 minute difference between batch time and submission time in spark streaming

spark version is 2.2.0
pseudocode:
read data1 from kafka with 5minute window
read data2 from kafka with 10minute window and 5miute slide duration
data1 join data2 on some condition
do some agg and write to mysql
question:
batch time is 15:00 but submitted time is 15:50, processing time is less than 1 minute. what happened?
val shareDs = KafkaUtils.createDirectStream[String, String](streamContext, LocationStrategies.PreferBrokers, shareReqConsumer)
val shareResDS = KafkaUtils.createDirectStream[String, String](streamContext, LocationStrategies.PreferBrokers, shareResConsumer).window(Minutes(WindowTime), Minutes(StreamTime))
shareDs doSomeMap join (shareResDs doSomeMap) forEachRddd{do some things then write to mysql}
there are some logs:

at the window timestamp, only do kafka re-partitions instead of add a job.

I resolved this problem.
Use spark-Streaming with kafka, congfig each stream with separate group_id and disable auto-commit,
Config kafka parameters appropriate. Especially heartbeat, session-timeout, request-timesout, max-poll-interval.

Why Cassandra TableWriter writing 0 records and how to fix it?

Why it is failing to save it sevaral times prior, how to tune it for production?

This is not a failure as noted by user10465355. When Spark breaks a job into Tasks it is possible that the work is not evenly distributed or that there isn't enough work for every task to have work to do. This results in some tasks being empty, so when they are processed by the Spark Cassandra Connector they write 0 rows.
For example say;
You read 100 records into 10 Spark Partitions/Tasks
You do a filter which eliminate values with a filter so now only 30 records remain in 5 tasks. The other 5 are empty.
When you write you will now only see records written for 5 tasks, and 5 tasks will report they had no rows written.

query takes a long time 'selecting' nothing

I have a query that I ran in thrift that takes a very long time. I run it on a single partition of a table which has 500k rows.
the query looks like this:
select col0 from <table> where partition=<partition> and <col1>=<val>
I made it so col1 != val, so the query returns 0 rows.
This query takes about a 30 seconds (a minute if I use select *).
When I run the exact same query but with select count(col0) it takes 2 seconds.
What could cause queries to take a long time with select col but not with select count(col)?
Here's the queries explained
explain select col0 from table where `partition` = partition and col=val;
*Project [col0#607]
+- *Filter (isnotnull(col1#607) && (col1#607 = aaaa))
+- *FileScan parquet table[col1#607,partition#611]
Batched: true,
Format: Parquet,
Location: PrunedInMemoryFileIndex[...,
PartitionCount: 23,
PartitionFilters: [isnotnull(partition#611),
(cast(partition#611 as int) = partition_name)],
PushedFilters: [IsNotNull(col1),
EqualTo(col1,aaaa)],
ReadSchema: struct
explain select count(col0) from table where `partition` = partition and col=val;
*HashAggregate(keys=[], functions=[count(col0#625)])
+- Exchange SinglePartition
+- *HashAggregate(keys=[], functions=[partial_count(col0#625)])
+- *Project [col0#625]
+- *Filter (isnotnull(col1#625) && (col1#625 = aaaa))
+- *FileScan parquet table[col1#625,partition#629]
Batched: true,
Format: Parquet,
Location: PrunedInMemoryFileIndex[...,
PartitionCount: 23,
PartitionFilters: [isnotnull(partition#629),
(cast(partition#629 as int) = partition_name)],
PushedFilters: [IsNotNull(col1),
EqualTo(col1,aaaa)],
ReadSchema: struct
As far as I can tell, the process is exactly the same, only the count query has more steps. So how come it's 15x faster?
Edit:
I found this interesting nugget in the logs:

(i.e. it repeats this block, looks like it runs tasks sequentially ant not in parallel like in the count case)
I also tried doing "order by" and it actually made the query run 2x faster
Running the same query on the same data using spark instead of thrift was much faster.
I run thrift on aws emr-5.11.1
Hive 2.3.2
Spark 2.2.1
thrift 0.11.0

Found the problem. I had this flag
spark.sql.thriftServer.incrementalCollect=true
in thriftserver. It collects the output from every worker sequentially which is what creates this massive overhead. Removing the flag fixed the issue. I guess it's optimized to not do is sequentially when doing "count", as it will necessarily not have a lot of data.

Why do tasks in the same task set have very different execution time?

I'm doing some kind of string processing on Spark. My code snippet:
val rdd = sc.objectFile[(String, String)]("some hdfs url", 1);
rdd.cache.count // let cache happen
val combOp = (f: List[String], g: List[String]) => {
for (x <- f) {
finder.processEntry(x)
}
for (x <- g) {
finder.processEntry(x)
}
finder.result
}
val res = rdd.mapPartitions( x => {
for (e<-x) {
finder.processEntry(e)
}
Iterator(finder.result)
}, true).reduce(combOp)
The dataset I have is about 10GB. I'm running Spark on a 24 cores machine, with 48GB memory. Configure file:
spark.driver.memory 1g
spark.executor.memory 30g
spark.executor.extraJavaOptions -Xloggc:/var/log/gcmemory.log -XX:+PrintGCDetails
spark.executor.cores 4

How can the first runners in the same task set execute longer than its latter runners? Any help is very much appreciated.

A common cause for stragglers (or executors that take longer for a certain partitions than others) is unevenly partitioner data. I'd suggest trying to repartition your data. The Spark UI may also have some helpful information (you can take a look at the input sizes etc.) Sometimes some machines are slower for random reasons (especially common in virtualized environments where we can have noisy neighbors on certain machines), you can try enabling speculative execution (see https://spark.apache.org/docs/latest/configuration.html) / set the spark.speculation flag so Spark can try and solve the problem on another executor if it happens to be running slowly on one machine.

Spark streaming app resets kafka offset continuously - apache-spark

It was from my redis server. After migration it became unstable and sometimes it was not working correctly. so I restarted the service and everything worked fine.
