Subject [jira] [Updated] (TEZ-1424) Fixes to DAG text representation in debug mode
Date Tue, 21 Oct 2014 04:55:33 GMT

     [ https://issues.apache.org/jira/browse/TEZ-1424?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Rajesh Balamohan updated TEZ-1424:
    Attachment: TEZ-1424.2.patch

Addressing review comments.

the ordering is changed where we log the debug after starting the DAG
Patch uses DAG_ID in the filename for correlating filename with the DAG.  If we have to use
DagPlan, we need to provide some unique number in the filename.

>          Issue Type: Bug
>            Reporter: Siddharth Seth
>            Priority: Critical
>         Attachments: TEZ-1424.1.patch, TEZ-1424.2.patch
> Several fixes required
> - Don't log entire tokens, just the identifier should be enough
> - DAG ID (or unique number needs to be used). Otherwise we get only one file per session
> - This should not go into the local-directory - since that isn't accessible. Instead
the log directory would be a better place.
> Marking as critical for 0.5.1 since this is very useful for debugging.
