Subject Re: Hbase hbck showing status as INCONSISTENT
Date Wed, 08 Jun 2011 17:21:40 GMT
A problem that will be fixed in 0.90.4 is that once hbck finds one
issue, all checks that follow emit 'INCONSISTENCY'.  A quick perusal
of the below has it that hbck is not able to reach a server.  Can you
check into that?  Its using an IP, rather than hostname.  Why is that?
 ips in the regionservers file?
