Failed to start Spark-shell

Failed to start Spark-shell - apache-spark

My goal is to run PySpark on my local machine. Following this tutorial I tried to install Spark from hereand get the winutils here. I added my SPARK_HOME and HADOOP_HOME to my list of environmental variables. My Java version is
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)
However, I tried to run spark-shell in CMD as administrator. I got the following error. Can someone tell me what I have done wrong ?
Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

I have the same issue on Spark 3.2.0.
I download spark 3.0.3 and adjust the SPARK_HOME on my environment variables (Windows) and I can have spark-shell at least running.

The above error occured and I have tried with different Hadoop winutils versions also but issue persists

spark-shell command throwing this error: SparkContext: Error initializing SparkContext

Spark version: 3.2.0
Java Version: 8
Python version: 3.7.3
Scala: sbt-1.5.5.msi
And I followed all the steps as per this link: https://phoenixnap.com/kb/install-spark-on-windows-10
When I run spark-shell command through cmd, it's throwing following error:
C:\spark-3.2.0-bin-hadoop3.2\bin>spark-shell
Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

Can someone please me understand if I'm missing out on something, some dependencies maybe? Thanks.

I encountered the same exception on Windows. I was using Spark version spark-3.2.1-bin-hadoop3.2 then I tried with,
spark-3.1.2-bin-hadoop3.2
Hadoop winutils.exe 3.2.0
Able to launch spark-shell successfully.
This article helped me.

Spark tgz spark-3.2.1-bin-hadoop3.2 to downgrade to spark-3.1.2-bin-hadoop3.2 has fixed

The problem is with the recent download files only. Change your Spark file and Winutils file to a previous version and the issue will get solved.
DOWNLOAD SPARK FILE - spark-2.4.6-bin-hadoop2.7.tgz FROM THIS URL - https://archive.apache.org/dist/spark/spark-2.4.6/
DOWNLOAD WINUTILS.EXE FILE FOR HADOOP 2.7 FROM THIS URL -
https://github.com/steveloughran/winutils/blob/master/hadoop-2.7.1/bin/winutils.exe
Once these files are changed, and point the environment variables to these files, the issue will get resolved.

Try downgrading your Spark version to the less recent one (2.8 works for me)

How can I use a saveAsTextFile() function in Apache Spark?

I am new in Spark, and I have some problems to register informations in a file.
The problem is the following:
I have declared the avglens RDD with the following command:
var avglens = sc.textFile("C:/Program Files/spark-3.1.1-bin-hadoop2.7/README.md")
.flatMap(line => line.split(' '))
.map(word => (word(0), word.length))
.groupByKey()
.map(pair => (pair._1, pair._2.sum/pair._2.size.toDouble))
then, I wanted to save informations of my avglens RDD in a new file named avglens-output.
To do that, I have launched the following command:
avglens.saveAsTextFile("avglen-output")
But, it returns the following error:

Also, a new folder avglens-output is created in my C:\Program Files\spark-3.1.1-bin-hadoop2.7\bin folder, but it is empty.
I don't understand why this errors appears, I have however authorized the writing on the bin folder.

Your problem seems to be in the map with word(0), not in the saveAsTextFile.
Since you are doing the split in the flatMap, the output of that step is a RDD with each word as a row, there is not an array for each element, just single word.
FlatMap flattens the array.
Check the difference
flatMap
scala> val rdd = sc.textFile("/Users/my_name/Workspace/spark-3.0.2-bin-hadoop2.7/README.md").flatMap(line => line.split(' '))
scala> rdd.take(5).foreach(println)
#
Apache
Spark
Spark
map
scala> val rdd = sc.textFile("/Users/sergio.couto/Workspace/spark-3.0.2-bin-hadoop2.7/README.md").map(line => line.split(' '))
scala> rdd.take(5).foreach(println)
[Ljava.lang.String;#7cd1d235
[Ljava.lang.String;#1736262a
[Ljava.lang.String;#7252e063
[Ljava.lang.String;#5edd0a7e
[Ljava.lang.String;#2c6f2bea
So you don't need to do word(0), it's not an array, you can just do word => (word, word.length)
Full Example:
val rdd = sc.textFile("/Users/my_name/Workspace/spark-3.0.2-bin-hadoop2.7/README.md")
.flatMap(line => line.split(' '))
.map(word => (word, word.length))
.groupByKey()
.map(pair => (pair._1, pair._2.sum/pair._2.size.toDouble))
scala> rdd.take(10).foreach(println)
(package,7.0)
(this,4.0)
(integration,11.0)
(Python,6.0)
(cluster.,8.0)
(its,3.0)
([run,4.0)
(There,5.0)
(general,7.0)
(YARN,,5.0)
Then you will be able to perform saveAsTextFile or whichever method you need

FileAlreadyExistsException while using Spark insertInto

I used following code to write a dataframe to a hive partitioned table by using pyspark Insertinto function.
spark.conf.set("spark.sql.sources.partitionOverwriteMode", "DYNAMIC")
df.write.mode("overwrite").insertInto(table, overwrite=True)
When the cluster is running some other heavy jobs. It has a 1/3 probability of error.
I think it maybe happens when the task seems to have failed but not fail indeed and yarn started another task to run this job.So two tasks conflict.
Traceback (most recent call last):

This issue is fixed in Spark 3.1.0.

how to fix ClassCastException while querying registered temp table with udf in zeppelin?

data.registerTempTable('tweets')
sqlContext.registerJavaFunction("clean","a.b.c.Cleaner")
sqlContext.sql("SELECT clean(tweet) from tweets").show()
The above code runs on jupyter successfully but not in zeppelin.
I have loaded "a.b.c.Cleaner" jar with z.load(..), also tweets table is being registered successfully, it is visible on sql context.
Here is the stacktrace from zeppelin:
Py4JJavaError: An error occurred while calling o1693.showString.
