Subject [jira] Commented: (HADOOP-4145) [HOD] Support an accounting plugin script for HOD
Date Fri, 12 Sep 2008 05:39:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12630487#action_12630487

Hemanth Yamijala commented on HADOOP-4145:
------------------------------------------

bq. The validation script would also require the number of nodes, queue and optionally estimated
walltime

Discussed this with Rob. We decided as this was not required for now, and will not require
a change to user interface when needed in future, we'll go with the existing approach of only
passing in account name. If more parameters are required, I'd actually prefer to think of
passing it in some generic way to scripts - because it is a plug-in hardcoding a specific
list of params might not be a good idea.

bq. It should fail with "Job Submission Failure"

Modified the exit code to 4, which is the closest we have to job submission failure. Atleast
both come in similar circumstances.

> Production environments have accounting packages to track usage of a cluster. HOD should
provide a mechanism to plug-in an accounting related script that can be used to verify if
the user is using a valid account or not.
