[jira] [Commented] (HIVE-19975) Checking writeIdList per table may
not check the commit level of a partition on a partitioned table
[ https://issues.apache.org/jira/browse/HIVE-19975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16525870#comment-16525870 ]
Sergey Shelukhin commented on HIVE-19975:
-----------------------------------------
Committed the patch to the branch that adds acid_stats test; this tests two scenarios I was looking at, the first part is the broken part, after the 2nd partition, explain doesn't use stats anymore.

> writeIdList is per table entity but stats for a partitioned table are per partition.
> I.e., each record in PARTITIONS has an independent stats.
> So if we check the validity of a partition's stats, we need to check in the context of
> a partiton.
