Zilong Zhu updated HDFS-17503:
------------------------------
Description:
When BlockSender throws an error because of OOM，the volume reference obtained
by the thread is not released，which causes the thread trying to remove the
volume to wait and fall into an infinite loop.
I found HDFS-15963 catched exception and release volume reference. But it did
not handle the case of throwing errors. I think "catch (Throwable t)" should be
used instead of "catch (IOException ioe)".
