Subject [jira] Commented: (HIVE-1609) Support partition filtering in metastore
Date Fri, 03 Sep 2010 01:49:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1609?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12905769#action_12905769

Carl Steinbach commented on HIVE-1609:
--------------------------------------

DynamicSerDe is the component that has a JavaCC dependency. I think DynamicSerDe (and TCTLSeparatedProtocol)
were deprecated a long time ago. Should we try to remove this code?

> The metastore needs to have support for returning a list of partitions based on user
specified filter conditions. This will be useful for tools which need to do partition pruning.
Howl is one such use case. The way partition pruning is done during hive query execution need
not be changed.
