Suresh Srinivas updated HDFS-781:
---------------------------------
Attachment: hdfs-781.rel20.patch
Attaching patch for branch 20. This patch has one difference from the trunk
version - in TestNameNodeMetrics.testFileAdd(), after deletion of the file, the
metrics "blocksTotal" is not expected to be set to 0. In 21 and trunk block
that belongs to a file is deleted immediately. In 20 this is done later on
receiving block report from the datanode.
> Metrics PendingDeletionBlocks is not decremented
