Subject [jira] [Commented] (YARN-3154) Should not upload partial logs for MR jobs or other "short-running' applications
Date Thu, 05 Mar 2015 05:24:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-3154?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14348169#comment-14348169

Xuan Gong commented on YARN-3154:

bq. how should an app handle stdout and stderr i.e. rotating of these files?

Yes, and this is the user's responsibility for this. All we need to do is to upload the logs
which exist.

bq.what regex format is supported? Will the NMClient do a sanity check to see if the format
is valid?

Support java regex. All the Include/Excludepatterns are defined in ASC.

> Currently, if we are running a MR job, and we do not set the log interval properly, we
will have their partial logs uploaded and then removed from the local filesystem which is
not right.
> We only upload the partial logs for LRS applications.
