I am using <spark.version>3.1.1</spark.version> with "delta" lake io.delta:delta-core_2.12:0.8.0. in my project.
While reading "delta" file I am getting below error
java.util.concurrent.ExecutionException:
org.apache.spark.SparkException: Job aborted due to stage failure:
ShuffleMapStage 4 ($anonfun$call$1 at DatabricksLogging.scala:77) has
failed the maximum allowable number of times: 4. Most recent failure
reason: org.apache.spark.shuffle.FetchFailedException:
java.lang.IllegalArgumentException: Unknown message type: 9 at
org.apache.spark.network.shuffle.protocol.BlockTransferMessage$Decoder.fromByteBuffer(BlockTransferMessage.java:71)
Any help , how to fix this issue?

I am currently using
export SPARK_HOME=/spark-folder/spark-3.0.2-bin-hadoop2.7-hive1.2
$SPARK_HOME/bin/spark-submit \
--master yarn \
--deploy-mode cluster \
...
--packages io.delta:delta-core_2.12:1.0.0
With Spark 3.1.1 you must use Delta 1.0.x - currently 1.0.0. 0.8.0 is compatible only with Spark 3.0.x (see compatibility matrix):
But most probably that you have an external shuffle service that is running on incompatible version of the Spark, like, your code is on 3.1.1, and shuffle service is on 3.0.x

I have tried upgrading to python 3.8 version and have also tried updating the java version. But none has worked.
I'm running a Spark job on Databricks which issues a NullPointerException without traces of my job's code. Would anybody know what would be the best course of action when it comes to debugging these issue?
The job is a Scala job running on Databricks Runtime 11.3 LTS, Spark 3.3.0
In case it's related with the issue, the job targets both AWS S3 and AWS Redshift for I/O.
Here's one of the stack traces
Job aborted due to stage failure: Task 267 in stage 30.0 failed 4 times, most recent failure: Lost task 267.3 in stage 30.0 (TID 6343) (10.218.226.53 executor 2): java.lang.NullPointerException

I've read answer about similar problem, but I don't understand what it means: java.lang.IllegalArgumentException: Too large frame: 5211883372140375593
I've also read about spark.sql.shuffle.partitions option, but it won't help me.

P.S. I appreciate all advices to make my pyspark tests better.
I've been trying to start spark-shell with Cassandra connector.
When I tried running it with spark-shell --packages com.datastax.spark:spark-cassandra-connector_2.12:3.1.0 or when I even compiled connector from https://github.com/datastax/spark-cassandra-connector and started like spark-shell --jars ~/.asdf/installs/spark/3.1.2/jars/spark-cassandra-connector-assembly-3.1.0-11-g53f24ce9.jar then I got this exception (both cases)

I tried to nslookup that IP but got no result. Can anyone tell me what's wrong or point me to working instructions that would allow me to start spark-shell session with working Cassandra connector?
Thanks
I found the problem. Spark-shell is trying to connect to spark-master and tries that IP address (which is eth0 of my machine at this time).
So the problem is that no spark-master job is available for spark-shell.
Your spark-shell command is incomplete. You need to specify the Spark master URL if you're connecting to a remote Spark cluster.
Here's an example that shows the minimum options you need to provide to launch a Spark shell:
$ spark-shell
--master <spark_master_url>
--packages com.datastax.spark:spark-cassandra-connector_2.12:3.1.0
--conf spark.sql.extensions=com.datastax.spark.connector.CassandraSparkExtensions
--conf spark.cassandra.connection.host=<cassandra_node_ip>
--conf spark.cassandra.auth.username=<cassandra_role>
--conf spark.cassandra.auth.password=<cassandra_password>
If your cluster doesn't have authentication enabled, you can leave out the username and password options. Cheers!
I'm testing a spark's "graceful decommission" feature for rdd blocks in kubernetes and getting an exception after sending a sigpwr signal to the executor.
