Kihwal Lee updated HDFS-9072:
-----------------------------
Attachment: HDFS-9072-br27.patch
The two test cases are also failing in branch-2.7. The trunk patch applies, but
its dependency, HDFS-9067, is not applicable to 2.7 as it is patching the
non-existant TestLazyWriter as well.
I am attaching the patch that includes {{DFSTestUtil.waitForMetric()}}.
