Before this change Impala always tried to fetch stats for row__id in full ACID tables, which does not exist in the metastore. Sometimes this led to an exception from HMS, see HIVE-28498 for details. This caused flakyness in test_compute_stats_with_structs. The test also had side effects (it computed stats for a shared table) so it was modified to use unique_database. Testing: - could reproduce the issue by starting HMS with hive.metastore.try.direct.sql=true and verified that the change fixes it Change-Id: I759f57c99aa16e4ab5fd82aa5f6b756446291f03 Reviewed-on: http://gerrit.cloudera.org:8080/21742 Reviewed-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>
