Subject Re: Running Hama on Hortonworks 2.0 distribution
Date Wed, 21 May 2014 08:01:28 GMT
Hi,

> attempt_201405201413_0006_000000_0: org.apache.hadoop.ipc.RemoteException(java.io.IOException):
File /tmp/hama-parts/job_201405201413_0005/part-3/file-0 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.

First of all, this means that you do not have DataNode process
running. See http://wiki.apache.org/hadoop/CouldOnlyBeReplicatedTo

P.S., And, please replace hadoop jar files in ${HAMA_HOME}/lib folder.
