> 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.
