Thanks [~jojochuang],
Attached new patch, reduce number of datanode, earlier it was using 9 DN's (6+3
policy), now it is using 3 DN's (2+1 policy). In my machine it is taking 3
seconds.

[~surendrasingh] I think the fix is good. But the test ran for more than 3
minutes on my machine. Can we update the test and cut down some wait time? It
doesn't look like a large integration test.

[~smeng] for review, attached updated patch.
{quote} Looking at the fix, this looks really bad.

[~jojochuang], do you have any other fix for this, I didn't get what is bad
here ?

Siyao Meng commented on HDFS-14687:

[~surendrasingh] Great work. Thanks for the patch. The fix looks good to me.
Unit test passed locally.
Just two minor issues:
1. Please address the checkstyle
[warnings|https://builds.apache.org/job/PreCommit-HDFS-Build/27409/artifact/out/diff-checkstyle-hadoop-hdfs-project_hadoop-hdfs.txt]
(line length).
2. Could you replace Thread.sleep(4000) in the test with either:
(1) another method that doesn't rely on timing, like what is done in
[HDFS-10240|https://github.com/apache/hadoop/commit/1290e3c647092f0bfbb250731a6805aba1be8e4b#diff-e069dc77becb87b909a07d27d3525236R1338];
(2) use a loop with small intervals (e.g. 100 ms) to check the status of
DataNode IBR until it finishes;
BTW I tried to remove Thread.sleep(4000) and ran the test. It passed as well
(locally on my Mac). Is this sleep() call necessarily? Please remove if not.
