Lost hbase table after restart
Hadoop: 0.20.2
Hbase: 0.20.4, r941076
Hi,
I've running a hbase table on 4 regionservers with 4 datanodes back cross on the same machines. After restart hbase and hadoop I've lost the one and only hbase table. The hbase-master-log says:

Hi Andrew,
You're right. I try to upgrade to the latest version.

Furthermore, be sure to read about what HBase 0.90.x requires: http://hbase.apache.org/notsoquick.html#requirements

Re: Lost hbase table after restart

Hi,
HBase 0.20.4 is very much out of date. It was released on 10 May 2010.
The current release is 0.90.2, released on 11 April 2011.
Why are you using such an out of date version?
For many many reasons you should be using the latest 0.90.x version.
Best regards,
- Andy
