Harsh J updated HDFS-4137:

    Target Version/s: 2.0.3-alpha

> BlockManager.chooseTarget's error message can be confusing

>                 Key: HDFS-4137
>                 URL: https://issues.apache.org/jira/browse/HDFS-4137
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>    Affects Versions: 2.0.2-alpha
>            Reporter: Jean-Daniel Cryans
>            Priority: Minor
> Consider this message:
> bq. org.apache.hadoop.ipc.RemoteException(java.io.IOException): File *somefile* could
only be replicated to 0 nodes instead of minReplication (=1).  There are 1 datanode(s) running
and no node(s) are excluded in this operation.
> Obviously a node was excluded but not in the sense that the Datanode treats it. Considering
that this is a message that noobs will see a lot, making it clearer will be a win.
