Re: hama system dir
I add the bsp.system.dir property to hama-site.xml, but the error
message remains there; directly mkdir /tmp/hadoop-<user>/bsp/system in
file system doesn't help either.
The version of hama and hadoop (hdfs and common) I am using is trunk;
zookeeper 3.3.1.
Previously I tried using hadoop 0.20.x (as instruction in getting
started - http://wiki.apache.org/hama/GettingStarted), but I notice in
that version I can not execute fs command e.g. `hadoop fs -ls /' There
is a hdfs property change which requires a patch; therefore I switch
to use trunk (patch has been added and I can add my changes as well).
Is there any restriction for hama to use hadoop version?
Or any other places that I can check regarding to this problem?
Thanks for help.

Hello,
> Is there any restriction for hama to use hadoop version?
Yes, the current trunk version only works on the hadoop-0.20.x.
Please try again with
http://apache.mirror.cdnetworks.com//hadoop/core/hadoop-0.20.2/
Thanks.

Re: hama system dir
Posted by Lin Chia-Hung <cl...@googlemail.com>.
After rolling back to use hadoop 0.20.2, I think this problem is solved.
But I notice that when executing the pi example `hama jar
build/hama-0.2.0-dev-examples.jar pi`, seems like it will stays
infinite at the state as below (it won't finish like hello example):
10/11/01 13:01:01 INFO bsp.BSPJobClient: Running job: job_201011011257_0002
Groom server processes are running on all machines and I can see the
estimated pi value printed in one of node's log. e.g.
2010-11-01 13:01:02,089 INFO
org.apache.hama.examples.PiEstimator$MyEstimator: Receives
messages:3.1372
2010-11-01 13:01:02,090 INFO org.apache.hama.examples.PiEstimator$MyEstimator:
Estimated value of PI is 3.1372
Is there any reason why it takes so a long time to accomplish a task?
