Dan Hecht updated IMPALA-7133:
------------------------------
Description:
An instance of this bug is that we see a "Default TException" error instead of
"Query Id ... Not Found" because of the following issue:
* get_results_metadata() does not declare that it throws BeeswaxException (it
declares throwing QueryNotFoundException)
* But our implementation actually throws that in the "Query Id ... Not Found"
case
* The Thrift C++ server has some logic that calls .what() on unknown exceptions
and wraps them into a TException
* On 3.x, we have THRIFT-727 in Thrift 0.9.3, which implements .what(), so the
original error message is present albeit wrapped in some garbage.
* On 2.x .what() does not return any useful information, so we just get a weird
empty message
