Subject [jira] [Commented] (HDFS-6085) Improve CacheReplicationMonitor log messages a bit
Date Tue, 11 Mar 2014 06:26:43 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6085?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13930011#comment-13930011

Colin Patrick McCabe commented on HDFS-6085:

bq. This looks good. Do you want to try lowering the log level for CacheManager#cacheRepors
in this patch as well? Right now it's pretty spammy at INFO, and I imagine it being even worse
on a large cluster.

I'll roll that into HDFS-6086.

bq. Otherwise, +1 pending.

Thanks, committed.

> It would be nice if the CacheReplicationMonitor logs would print out information about
blocks when at TRACE level.  We also could be a bit more organized about logs and include
the directive ID in the log, so that it was clear what each log message referred to.
