---------------------------------------
Summary: Merging Statistics are promoted to COMPLETE (most of the
time)
Key: HIVE-17934
URL: https://issues.apache.org/jira/browse/HIVE-17934
Project: Hive
Issue Type: Bug
Components: Statistics
Reporter: Zoltan Haindrich
in case multiple partition statistics are merged the STATS state is computed
based on the datasize and rowcount;
the merge may hide away non-existent stats in case there are other partition or
operators which do contribute to the datasize and the rowcount.
