[jira] [Commented] (HDFS-6877) Avoid calling checkDisk and stop active BlockReceiver thread when an HDFS volume is removed during a write.

["Colin Patrick McCabe (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDFS-6877?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14145704#comment-14145704 ] 

Colin Patrick McCabe commented on HDFS-6877:
--------------------------------------------

I don't understand why you are sending InterruptedException to writers, can you clarify?  Writers shouldn't linger more than a minute or two and no new ones will be added once the volume is removed.  You're not even blocking until they've exited, so this doesn't simplify the locking.
