------------------------------------------
> if the client has a write but datanodes in the pipeline hang, this patch does
> not solve the problem
You are right.
> Maybe it makes sense to do it in RPC clients.
The clients currently use the streaming API to send data to the datanode(s).
Are you saying that the client should periodically ping each of the datanode(s)
using a RPC?
> Should DFS outputstream's close wait forever?

> Currently {{DFSOutputStream.close()}} waits for ever if Namenode keeps
> throwing {{NotYetReplicated}} exception, for whatever reason. Its pretty
> annoying for a user. Shoud the loop inside close have a timeout? If so how
> much? It could probably something like 10 minutes.
