[jira] Commented: (HADOOP-4556) Block went missing

    [ https://issues.apache.org/jira/browse/HADOOP-4556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12645653#action_12645653 ] 

Raghu Angadi commented on HADOOP-4556:
--------------------------------------

Couple of minor comments :

- The debug comment removed while choosing excess replicas can be retained and changed to INFO level. This is a pretty useful log.
- in removeFromInvalidates(), we need to log only if remove() returns true. Usually it will be false.

I am trying to see one of the actual cases seen will be fixed by this patch.
