[jira] [Created] (SPARK-20871) Only log Janino code in debug mode

Glen Takahashi created SPARK-20871:
--------------------------------------

             Summary: Only log Janino code in debug mode
                 Key: SPARK-20871
                 URL: https://issues.apache.org/jira/browse/SPARK-20871
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.1.1
            Reporter: Glen Takahashi


Currently if Janino code compilation fails, it will log the entirety of the code in the executors. Because the generated code can often be very large, the logging can cause heap pressure on the driver and cause it to fall over.

I propose removing the "$formatted" from here: https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/codegen/CodeGenerator.scala#L964
