[jira] [Created] (HIVE-20896) CachedStore fail to cache stats in
multiple code paths
Daniel Dai created HIVE-20896:
---------------------------------
Summary: CachedStore fail to cache stats in multiple code paths
Key: HIVE-20896
URL: https://issues.apache.org/jira/browse/HIVE-20896
Project: Hive
Issue Type: Bug
Components: Standalone Metastore
Reporter: Daniel Dai
Assignee: Daniel Dai
Bunch of issues discovered in CachedStore to keep up column statistics:
1. The criteria for partition/non-partition is wrong (table.isSetPartitionKeys() is always true)
2. In update(), partition column stats are removed when populate table basic stats
3. Dirty flags are true right after prewarm(), so the first update() does not do anything
4. Could invoke cacheLock without holding the lock, which results a freeze in update()
