Subject Re: failed to run hama pi example
Date Wed, 12 Sep 2012 06:48:57 GMT
Thanks so much, Edward.

I fellowed your suggestion and instanlled a hadoop 0.20.2 instead for Hama.
However, this time when I start Hama, a fatal happened and the bspmaster
daemon can not start up. The corresponding error message in the baspmaster
log file shows as below.
