Subject [jira] Commented: (HIVE-680) add user constraints
Date Mon, 28 Feb 2011 15:14:36 GMT

    [ https://issues.apache.org/jira/browse/HIVE-680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13000322#comment-13000322

Tim Robertson commented on HIVE-680:
------------------------------------

I should add that the workaround was to add "id IS NOT NULL" to a few queries and all was
happy, and longer term we will address the root cause and escape those characters.

> Many times, because of a few bad input rows, the whole job fails and it takes a long
time to debug those.
> It might be very useful to add some constraints, which can be checked while reading the
data.
> An option can be added to ignore configurable number of bad rows.
