sam rash updated HADOOP-6762:
-----------------------------
Attachment: hadoop-6762-7.txt
1. changed to use Future.get() w/o timeout
2. static executor instance with cached thread instances (with daemon thread
factory)
3. added catch of interruptedException around sendParams call to avoid
undeclared throwable exception
note : used a dedicated lock var around the submit + wait for a sendParams
call. I didn't want to worry about reasoning through lock contention/deadlock
with synchronized methods (why I didn't synchronize on "this")
> exception while doing RPC I/O closes channel
> --------------------------------------------

> If a single process creates two unique fileSystems to the same NN using
> FileSystem.newInstance(), and one of them issues a close(), the leasechecker
> thread is interrupted. This interrupt races with the rpc namenode.renew()
> and can cause a ClosedByInterruptException. This closes the underlying
> channel and the other filesystem, sharing the connection will get errors.
