Subject Re: Problems with Rumen in Hadoop-0.21.0
Date Fri, 23 Dec 2011 11:46:44 GMT
Finally I've found why we can't use rumen in Hadoop-0.21, I've just seen
the logs of hadoop-0.20 and compared them with those of 0.21, then I found
there is a BIG difference between them in the format, that's why we can't
use rumen in 0.21.

BTW, the logs' format in 0.23 has also changed a little bit.

Regards,
Sophie
