Hbase fbck gives orphan region error

[Shengjie Min <ke...@gmail.com>]

Hi,

I have a hbase table called "test", everytime when I deploy my cluster, I
do a hbase fbck 1st before I create the actual "test" table. But now when I
did a fresh deployment (destroy all the vms and recreate the cluster), I
got the following error. I am confused why I am get orphan region error in
a fresh deployment? Where the leftover is coming from.

Hello Shengie,

        Also make sure your HDFS is out of the safemode.

Hi Shengie,

Can you take a look, using hadoop, at what is inside this directory?

/hbase/test/75b34fd47e7df5e63e4e0ec1d960b905
