Hi Eric and Michael:
I run into this problem with Spark 1.4.1 too. The error stack is:
java.lang.NoClassDefFoundError: Could not initialize class
org.apache.spark.sql.catalyst.expressions.codegen.GeneratePredicate$
at
org.apache.spark.sql.execution.SparkPlan.newPredicate(SparkPlan.sc
Okay, thank you Micheal.

Those are probably related. It looks like we are somehow not being thread
safe when initializing various parts of the scala compiler.
Since code gen is pretty experimental we probably won't have the resources
to investigate backporting a fix. However, if you can reproduce the
problem in Spark 1.
Yes, it's always appears on a part of the whole tasks in a stage(i.e. 100/100
(65 failed)), and sometimes cause the stage to fail.
And there is another error that I'm not sure if there is a correlation.
java.lang.NoClassDefFoundError: Could not initialize class
org.apache.spark.sql.catalyst.expre
Interesting, I believe we have run that query with version 1.1.0 with
codegen turned on and not much has changed there. Is the error
deterministic?

Hi Michael,
We use Spark v1.1.1-rc1 with jdk 1.7.0_51 and scala 2.10.4.

What version of Spark SQL?

Hi all,
We run SparkSQL on TPCDS benchmark Q19 with spark.sql.codegen=true, we got
exceptions as below, has anyone else saw these before?
java.lang.ExceptionInInitializerError
