Doug Cutting resolved HADOOP-457.
---------------------------------
Resolution: Cannot Reproduce
> Unable to create file in dfs in code run on machine not in the cluster.
> -----------------------------------------------------------------------
>
> Key: HADOOP-457
> URL: http://issues.apache.org/jira/browse/HADOOP-457
> Project: Hadoop
> Issue Type: Bug
> Components: dfs
> Affects Versions: 0.5.0
> Reporter: Johan Oskarson
>
> I've got a tiny hadoop cluster and one machine that's not in the cluster that
> rsync the latest version off the namenode/jobtracker machine. The machine
> that's not in the cluster is then responsible for starting a few jobs here
> and there.
> However, the latest trunk is unable to create files in the dfs from my code.
> I'm using a simple new OutputStreamWriter(fs.create(file))); and the file
> creation looks like it's going ok but then this gets thrown:
> org.apache.hadoop.ipc.RemoteException: java.io.IOException: failed to create
> file
> /user/hadoop/submissions/1150000000/1152000000/1152440000/.1155824015.negsub.crc
> on client "servernotincluster" because target-length is 0, below
> MIN_REPLICATION (1)
> at org.apache.hadoop.dfs.FSNamesystem.startFile(FSNamesystem.java:410)
> at org.apache.hadoop.dfs.NameNode.create(NameNode.java:202)

> If I add that machine to the conf/slaves it works fine. Note that it's trying
> to create that file on the server that's not in the cluster.
