Subject [jira] Updated: (MAPREDUCE-927) Cleanup of task-logs should happen in TaskTracker instead of the Child
Date Mon, 08 Mar 2010 10:59:27 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-927?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amareshwari Sriramadasu updated MAPREDUCE-927:
----------------------------------------------

    Attachment: patch-927-3.txt

Patch merged with trunk and incorporates most of the comments.

bq. addJobLogsForDeletion() should not itself take jobcompletion time, it should instead be
taken from clock.
I think it makes sense to pass this as a parameter. In future, we should get job completion
time from JobTracker.

bq. TestTaskTrackerLocalization.verifyUserLogsCleanup(): shouldn't you be setting the clock
and use an inline cleaner?
bq. Should use clock and inline clear similar to the last comment above
Tests already use inline cleanup.

> Task logs' cleanup is being done in Child now. This is undesirable atleast for two reasons:
1) failures while cleaning up will affect the user's tasks, and 2) the task's wall time will
get affected due to operations that TT actually should own.
