Subject [jira] Commented: (PIG-94) Pig Streaming functional spec proposal
Date Wed, 19 Mar 2008 14:08:24 GMT

    [ https://issues.apache.org/jira/browse/PIG-94?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12580379#action_12580379

Pi Song commented on PIG-94:

Very good work to review.

Here are my suggestions:-
- In the parser, EXECCOMMAND doesn't seem to accept backtick escape characters. Do plan to
have it or just say backticks aren't allowed?
- Agree with Alan to have a timeout mechanism. You already have got the outputBytes variable
in PigExecutableManager. Possibly just use it to monitor the movement.
- The error handling logic by just printing out on work load nodes will not be visible to
Pig user.
- This following line in HadoopExecutableManager will not work on Windows:-
FileUtil.chmod(executable.toString(), "a+x");
