----------------------------------
Summary: get_aggr_stats_for doesn't aggregate stats when direct
sql batch retrieve is enabled
Key: HIVE-29203
URL: https://issues.apache.org/jira/browse/HIVE-29203
Project: Hive
Issue Type: Bug
Components: Standalone Metastore
Reporter: Zhihua Deng
In case of metastore.direct.sql.batch.size > 0, and number of partition names
or columns in get_aggr_stats_for is bigger than the
metastore.direct.sql.batch.size, then the
AggrStats from the call get_aggr_stats_for might have un-merged stats for the
same column, so the aggregated stats is not correct, which may make CBO
generate an outdated execution plan.
