----------------------------------------------

Thanks for checking the defect.

Yes, these are in datanode.

The same problem will exist for any client that is using ipc.Client.

So I feel we can add some configuration to retry for that specific interval so that as per
the need.

> When NN/DN is shutdown gracefully, the DFSClient operations which are waiting for a response
from NN/DN, will throw exception & come out quickly
> But when the NN/DN network is unplugged, the DFSClient operations which are waiting for
a response from NN/DN, waits for ever.
