Tsz Wo Nicholas Sze updated HDFS-7358:
--------------------------------------
    Attachment: h7358_20141104.patch

Tried to change TestByteArrayManager but not able to reproduce the bug.

However, I did find a bug in the test -- it should not call Future.get() when holding a lock.

h7358_20141104.patch: fixes TestByteArrayManager and changes notifyAll() to notify().
