Subject Re: can't start hbase after crash
Date Fri, 31 Oct 2014 17:05:48 GMT

>From the following error, it means region 69e9a7efb9ee00b1ecfe50f825e7cc5b
is opening and can¹t serve any request. There are may some issues
preventing the region from being opened. You can check Region Server log
to see why 69e9a7efb9ee00b1ecfe50f825e7cc5b can¹t be opened.
