Subject [jira] Commented: (HIVE-705) Let Hive can analyse hbase's tables
Date Wed, 03 Mar 2010 20:14:27 GMT

    [ https://issues.apache.org/jira/browse/HIVE-705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12840848#action_12840848
] 

John Sichi commented on HIVE-705:
---------------------------------

Prasad, the MetaHook interface is defined that way so that if a handler wants to, it can carry
out the operation in a stateful fashion (e.g. if its underlying catalog supports transactions),
but there is no requirement for it to keep state, and in fact the HBaseStorageHandler implementation
is itself stateless (and has a NOP for three of its method implementations).

Alter table:  yes, I'm planning to create a followup task for this.  The original patch had
alter table support in the meta hook interface too, but I trimmed it down for now to limit
the scope of the first commit.
