Subject [jira] [Commented] (HDFS-4563) Update namespace/diskspace after deleting snapshots
Date Mon, 11 Mar 2013 04:07:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13598515#comment-13598515
] 

Tsz Wo (Nicholas), SZE commented on HDFS-4563:
----------------------------------------------

Let's change Processor<E> to Processor<E, C> and pass the counts with type C in
process(..), i.e.
{code}
public void process(E element, C counts);
{code}
Then, we don't have to import Quota.Count in Diff.
