Subject hama pi Job failed
Date Fri, 06 Sep 2013 07:36:35 GMT
Dear all,

I am a new user of hama, te Hadoop and hama were installed and running
successfully but when I am trying to execute pi example to test hama
cluster I am getting the following:
>/home/hadoop/hama-0.6.2/bin/hama jar hama-examples-0.6.2.jar pi

13/09/06 12:21:34 INFO bsp.BSPJobClient: Job failed.

In the log file:
cat hama-hadoop-bspmaster-hmaster.log

Let me also mention that the cluster contains one Namenode and one Datanode
and this is the output of jps on each of them:
Namenode:
6039 BSPMasterRunner
2068 NameNode
2727 TaskTracker
6272 Jps
2550 JobTracker
5989 ZooKeeperRunner
2241 DataNode
2424 SecondaryNameNode
Datanode:
2303 DataNode
12864 GroomServerRunner
13126 Jps

I will appreciate any help or suggestion to solve this issue.

Thanks in advance.

Regards,
 Vahe
