Michael Smith commented on IMPALA-12878:
----------------------------------------
I tried doing that in FinishUnregisterQuery. I think the challenge is that our
clients don't have a good way to control closing a query twice. There seems to
be some flow where Thrift's RPC will automatically close a connection,
triggering session expiration and closing the query, then an explicit
close_query can trigger this case.
