Description

I'm trying to debug failure queries where an IllegalStateException is thrown wrapping a NullPointerException from an "invalidate metadata <table>" query.

The error message shows up in impala-shell but it doesn't appear that the Java backtrace is logged anywhere in the logs. This makes it impossible to determine where the NPE has come from.
