Jing Zhao updated HDFS-4059:
----------------------------
Attachment: HDFS-4059.trunk.001.patch
The patch includes a new testcase (testStaleNodes) for TestNameNodeMetrics. But
on my local test TestNameNodeMetrics#testCorruptBlock may still fail. After
applying the patch in HDFS-2434 my local test works fine.
