Subject [jira] [Updated] (MAPREDUCE-4296) remove old aggregated logs
Date Wed, 15 Aug 2012 14:32:38 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4296?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Robert Joseph Evans updated MAPREDUCE-4296:

    Target Version/s: 0.23.3, 2.1.0-alpha  (was: 0.23.3)
        Release Note: 
When upgrading if log aggregation is enabled and yarn.log-aggregation.retain-seconds is so
that logs are going to be deleted, a cluster administrator should change the permissions on
all user's logs to be 770.

hadoop fs -chmod -R 770 <log-dir>/*

Please be sure that <log-dir> itself is not modified.

> Currently the aggregated user logs under NM_REMOTE_APP_LOG_DIR are never removed.  We
should have mechanism to remove them after certain period.
> It might make sense for job history server to remove them.
