Subject Re: [VOTE] RC2 for the Apache Hama 0.4-incubating release
Date Sat, 04 Feb 2012 14:50:32 GMT
Sorry my bad. I falsely put -jar instead of jar in the command line.
This problem now is solved.

RC2 outputs ok on my env (4 vms where 1 bspmaster, 2 grooms and 1 for zk)

12/02/04 22:46:38 INFO bsp.BSPJobClient: Running job: job_201202042245_0001
12/02/04 22:46:41 INFO bsp.BSPJobClient: Current supersteps number: 0
12/02/04 22:46:47 INFO bsp.BSPJobClient: Current supersteps number: 1
12/02/04 22:46:47 INFO bsp.BSPJobClient: The total number of supersteps: 1
Estimated value of PI is	3.1481999999999997
Job Finished in 9.335 seconds

But  I notice that it seems in grooms there has error e.g.

attempt_201202042245_0001_000002_0 Error reading child output
java.io.IOException: Stream closed

This does not prevent finishing execution, but looks like the log
stream is already closed.
