[jira] Created: (HADOOP-1068) Improve error message for 0 datanode
case
Improve error message for 0 datanode case
-----------------------------------------
Key: HADOOP-1068
URL: https://issues.apache.org/jira/browse/HADOOP-1068
Project: Hadoop
Issue Type: Improvement
Components: dfs
Affects Versions: 0.12.0
Reporter: Owen O'Malley
Assigned To: dhruba borthakur
Fix For: 0.13.0
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.

---------------------------------------
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.
