------------------------------------------
Summary: Queries in state "waiting to be closed" still hold ACID
locks
Key: IMPALA-11423
URL: https://issues.apache.org/jira/browse/IMPALA-11423
Project: IMPALA
Issue Type: Bug
Reporter: Zoltán Borók-Nagy
Impala queries that are in state "Waiting to be closed" still keep the ACID
transactions open (and hold locks).
>From the documentation:
_These queries are no longer executing, either because they encountered an
error or because they have returned all of their results, but they are still
active so that their results can be inspected. To free the resources they are
using, they must be closed._
But the ACID-resources like transactions and locks should be freed as soon as
possible, no need to wait for the client to invoke close() on the query handle.
