Subject [jira] Commented: (PIG-608) Compile or validate the whole script before execution
Date Wed, 07 Jan 2009 21:22:44 GMT

    [ https://issues.apache.org/jira/browse/PIG-608?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12661714#action_12661714

Yiping Han commented on PIG-608:
--------------------------------

Alan, I think that's the problem. Everything up to a store or dump is checked but if there
is an error after that, it will be reported until the previous store or dump finished. I don't
think this is a duplicate of PIG-607, but I agree the fix to PIG-607 might be able to fix
this problem (depends on the actual solution).

> This is a very usual scenario: 
> We are running a big pig job that contains several hadoop jobs. It has been running for
long times and the first hadoop job sucess, then suddenly pig report it found a syntax error
in the script after the first hadoop job...we have to repeat from the beginning.
> It would be nice if pig can compile to the end of the script, find all the syntax error,
type mismatch, etc., before it really starts execution.
