Sahil Takiar commented on HIVE-18915:
-------------------------------------
One comment, when creating the {{HiveException}} for
{{SPARK_CREATE_CLIENT_ERROR}} you probably want to use
{{Throwables#getRootCause}} as the root cause exception is often the most
relevant.
It would be nice (but not necessary) to have a negative CLI driver test for
this, we basically need a way to force a failure in the spark-submit code-path.
