Subject [jira] Commented: (HIVE-1849) add more logging to partition pruning
Date Tue, 14 Dec 2010 18:19:02 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1849?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12971352#action_12971352

Ashutosh Chauhan commented on HIVE-1849:
----------------------------------------

bq. In facebook, we are seeing some intermittent errors, where it seems that either all the
partitions are not returned by the metastore or some of them are pruned wrongly. 

It would be good to know if the errors you were seeing were indeed because of partition pruning
code in Metastore.
