[SPARK-11188][SQL][WIP] Elide stacktraces in bin/spark-sql for
AnalysisExceptions
I have a couple of questions.
1) I have used the a newly added constructor in hive that takes the
additional parameter
Throwable to construct a CommandProcessorResponse which i use to
match in the caller to find out if the type of exception is
AnalysisException.
Question : Can this code run under an earlier version of Hive ? In
which case this
will trigger a MethodNotFound exception.
If the answer to above question is yes, then i can think of a couple
of options. Please
let me know if there is a preference or a different way.
1) We create a wrapper class that holds CommandProcessorResponse and a
throwable
that we use to match later. We also create a wrapper method to
Driver.run() that
returns CommandProcessorResponseWrapper.I prefer this option as it
seems cleaner.
2) We search for AnalysisException in the exception string
2) The actual exception is also logged in run method of the SparkSQLDriver.
If the
logging is set to CONSOLE then the exception is printed on the screen.
I hope this is ok ?
3) Is there a way to test this ? Since we only suppress printing of the
stack trace , i didn't find a way to hook into any existing test suite.
