Re: Add jar files on classpath when submitting tasks to Spark
Well if you look at the spark-shell script this is what it says
# SPARK-4161: scala does not assume use of the java classpath,
# so we need to add the "-Dscala.usejavacp=true" flag manually. We
# do this specifically for the Spark shell because the scala REPL
# has its own class loader, and any additional classpath specified
# *through spark.driver.extraClassPath is not automatically propagated.*
Whether this is relevant or not I am not sure

RE: Add jar files on classpath when submitting tasks to Spark
Thank you for the example.
I am able to submit the task when using the –jars parameter as followed:
spark-submit --class com.infor.skyvault.tests.LinearRegressionTest --master
local –jars path/to/jar/one;path/to/jar/two
C:\_resources\spark-1.0-SNAPSHOT.jar -DtrainDataPath="/path/to/model/data"
But, I would like to find out, why the setting of spark.driver.extraClassPath
attribute in spark-defaults.xml is not applied when submitting the task.
In our scenario let’s assume that all workers (currently only one worker) have
the attribute spark.driver.extraClassPath set to the same path and the folder
on all workers contains the same .jar files.
Thank you for your help,
Regards,
Jan

you can do that as long as every node has the directory referenced.

RE: Add jar files on classpath when submitting tasks to Spark
Thank you for the reply. I am aware of the parameters used when submitting the tasks (--jars is working for us). But, isn’t there any way how to specify a location (directory) for jars „in global“ - in the spark-defaults.conf??

In my spark-defaults.conf file I have configuration: spark.driver.extraClassPath = path/to/folder/with/jars all jars in the folder are available in SPARK-SHELL The problem is that jars are not on the classpath for SPARK-MASTER; more precisely – when I submit any job that utilizes any jar from external folder, the java.lang.ClassNotFoundException is thrown. Moving all external jars into the jars folder solves the situation, but we need to keep external files separatedly. Thank you for any help Best regards, Jan
Re: Add jar files on classpath when submitting tasks to Spark
There are options to specify external jars in the form of --jars, --driver-classpath etc depending on spark version and cluster manager.. Please see spark documents for configuration sections and/or run spark submit help to see available options.
