> sometimes time out.
> This is happening on trunk as can be observed in several recent jenkins job. 
> (e.g. https://builds.apache.org/job/Hadoop-Hdfs-trunk/2423/  
> https://builds.apache.org/job/Hadoop-Hdfs-trunk/2386/ 
> https://builds.apache.org/job/Hadoop-Hdfs-trunk/2351/ 
> https://builds.apache.org/job/Hadoop-Hdfs-trunk-Java8/472/
> On my local Linux machine, this test case times out 6 out of 10 times. When 
> it does not time out, this test takes about 20 seconds, otherwise it takes 
> more than 60 seconds and then time out.
> I suspect it's a deadlock issue, as dead lock had occurred at this test case 
> in HDFS-5527 before.
