Subject [jira] Commented: (HIVE-1100) Make it possible for users to retry map-reduce jobs in a single Hive query
Date Tue, 26 Jan 2010 01:28:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12804838#action_12804838
] 

Namit Jain commented on HIVE-1100:
----------------------------------

Is it a timeout based approach ? When does the cleanup happen if the client never issues a
clear/continue ?
Do we need to enhance explain plan or some other tool so that the client knows which tasks
will the query execute ?

> Sometimes a single hive query get compiled into several map-reduce jobs, and one of the
jobs failed because of some transient errors.
> Users would need to start from scratch.
> We should allow the user to start from the point of failure to continue the query.
