> 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.
