> Came across this situation (with a version of 0.96 very close to RC5 version
> created on 10/11):
> The sequence of events that happened:
> 1. The hbck tool couldn't communicate with the RegionServer hosting namespace
> region due to some security exceptions. hbck INCORRECTLY assumed the region
> was not deployed.
> In output.log (client side):
> {noformat}
> 2013-10-12 10:42:57,067|beaver.machine|INFO|ERROR: Region { meta =>
> hbase:namespace,,1381564449706.a0ac0825ba2d0830614e7f808f31787a., hdfs =>

> deployed => } not deployed on any region server.
> 2013-10-12 10:42:57,067|beaver.machine|INFO|Trying to fix unassigned region...
> {noformat}
> 2. This led to the hbck tool trying to tell the master to "assign" the region.
> In master log (hbase-hbase-master-gs-hdp2-secure-1381559462-hbase-12.log):
> {noformat}

> 3. The master went through the steps - sent a CLOSE to the RegionServer
> hosting namespace region.
