Subject [jira] [Commented] (HIVE-8863) Cannot drop table with uppercase name after "compute statistics for columns"
Date Thu, 20 Nov 2014 01:09:35 GMT

    [ https://issues.apache.org/jira/browse/HIVE-8863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14218826#comment-14218826

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?
