Re: Hbase with Hadoop
Ramya Sunil 2011-10-13, 03:51
Hi Jignesh,

I have been running quite a few hbase tests on Hadoop 0.20.205 without any
issues on both secure and non secure clusters.

I have seen the error you mentioned when one has not specified the hbase
config directory.

Can you please try "hbase --config <path to hbase config directory> shell"
and check if that solves the problem?

Thanks
Ramya
