Subject Re: Container allocation fails randomly
Date Thu, 19 Sep 2013 05:55:09 GMT
Hi Omkar,

  It is my own custom AM that I am using, not the MR-AM. But I am still not
able to believe how can a negative value go from the getProgress() call
which is always calculated from division of positive numbers, but might be
some floating point computation problems as you are saying.

Thanks,
Kishroe
