------------------------------------------
Summary: Handling partition level stat replication
Key: HIVE-21775
URL: https://issues.apache.org/jira/browse/HIVE-21775
Project: Hive
Issue Type: Sub-task
Components: HiveServer2, repl
Affects Versions: 4.0.0
Reporter: mahesh kumar behera
Assignee: mahesh kumar behera
Fix For: 4.0.0
Statistics for table is maintained for all the partitions. The table level
basic stats present in the table has the combined data for all the partitions.
When only a few partitions are replicated, the replicated stats for the table
may not be correct. In case of partition column stats, the aggregate stats from
the partitions stats table will not correct. So the statistics replication can
not be supported in case of partition levee replication.
TODO : Need to check how to handle it.
