Subject [jira] [Updated] (HDFS-6877) Avoid calling checkDisk when an HDFS volume is removed during a write.
Date Wed, 22 Oct 2014 07:03:34 GMT

]

Lei (Eddy) Xu updated HDFS-6877:
--------------------------------
    Attachment: HDFS-6877.007.patch

[~cmccabe] Thanks for your great advices. I changed the patch to enforce the logic that the
ReplicaNotFoundException must be thrown when the volume for the block has been removed. 

Would you please take another look?
