Subject: how to debug Hama Jobs?


This is Min Tu and I am new to Hama. I have developed a Hama graph job and it works fine with
simple testing data but failed with real data.

I have looked several places for the reason including

$HAMA_HOME/logs where BSP server is running

$HAMA_HOME/logs where Groom Server is running
$HAMA_HOME/logs/tasklogs/job_ID where Groom server is running

But I can not find the Exception or why the job failed.

Would  you please provide some suggestions? Thank you very much for the help
