Owen O'Malley updated HADOOP-581:
---------------------------------
Attachment: dfs.patch
This patch adds a catch for IOException in the Datanode's offerService loop. It
also moves clearing the blockReceived list until the call to the name node
completes.
> Datanode's offerService does not handle rpc timeouts

> The Datanode's offerService routine needs to protect itself (with log &
> ignore) from IOExceptions (especially RPC timeouts) in the offer service
> method.
> Currently, if a heartbeat times out, the Datanode will "reset" itself, which
> means that the full block report must be sent again.
