Johan Oskarson commented on HADOOP-601:
---------------------------------------

Any news on this one?

Whenever the jobtracker is busy and it makes our JobClient.submitJob calls fail.
This in turn means a whole chain of jobs that depends on that submit fails, it's a big issue
when it comes to using hadoop in production.

> We need some mechanism for RPC calls that get exceptions to automatically retry the call
under certain circumstances. In particular, we often end up with calls to rpcs being wrapped
with retry loops for timeouts. We should be able to make a retrying proxy that will call the
rpc and retry in some circumstances.
