Owen O'Malley commented on HADOOP-1068:
---------------------------------------
Your message is an improvement, but I would still prefer a special case for 0
datanodes, since that is a case that can easily happen if the cluster is
misconfigured.

> A user got the error message:
> org.apache.hadoop.ipc.RemoteException: java.io.IOException: failed to create
> file /user/root/rand-input/part000000 on client localhost.localdomain
> because target-length is 0, below MIN_REPLICATION (1)
> A better error message for 0 targets would be something like:
> The cluster has no datanodes for creating file
> /user/root/rand-input/part000000.
