Ashutosh Chauhan commented on HIVE-8863:
----------------------------------------
Patch looks good. But it seems we might have problem for partitioned table as
well, looking at ObjectStore::deletePartitionColumnStatistics() which looks
like suffer from same casing problem
{code}
mStatsObj =
(MPartitionColumnStatistics)query.executeWithArray(partName.trim(),
dbName.trim(),
tableName.trim(), colName.trim());
{code}
Can you test dropping a particular partition of a table which has statistics as
well as dropping a partition table altogether?
