Subject [jira] Commented: (PIG-1565) additional piggybank datetime and string UDFs
Date Thu, 26 Aug 2010 22:48:58 GMT

    [ https://issues.apache.org/jira/browse/PIG-1565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12903123#action_12903123

Alan Gates commented on PIG-1565:
---------------------------------

Comments
# ErrorCatchingBase swallows any non-ExecExceptions.  It should print their messages out as
warnings.  Warnings are collated and the count reported at the end of the job.  Details are
only printed if the user asks for them.  That way the user will still be informed that something
unexpected happened and can investigate further if he wants to.
# On the duplication, it looks to me like INDEX_OF and LAST_INDEX_OF are supersets of the
functions already in Pig.  You could submit a patch for those two functions (which are now
builtins) to extend them to take the optional third argument.  SPLIT_ON_REGEX looks like a
subset of the existing SPLIT function that is built into Pig, so other than having it as an
alias so that Amazon users who are used to calling SPLIT_ON_REGEX I'm not clear what the value
is.

Thanks for contributing all these, this is great.

I'll run test-patch and the unit tests and post the results.
