Amareshwari Sri Ramadasu updated HADOOP-1898:
---------------------------------------------
Attachment: patch-1898.txt
I did the changes for locking ReflectionUtils. Here static synchronized
method is replaced by a method in a class object. This would not be
conservative locking now.
> locking for the ReflectionUtils.logThreadInfo is too conservative

> When the RPC servers get into trouble with their call queues backing up, they
> occasionally dump the call stacks. These are very useful for identifying hot
> spots, but the locking is too conservative and so all of the handlers are
> blocked while the thread call stacks are dumped.
