> The cluster can not start up because there are no active master. The active master can
not finish initialing because the hbase:namespace region can not be assign. 
> In TestClusterId unit test, TEST_UTIL.startMiniHBaseCluster set new hbase root dir. But
the regionserver thread which stared first used  a different hbase root dir. If assign hbase:namespace
region to this regionserver, the region can not be assigned because there are no tableinfo
on wrong hbase root dir.
> When regionserver report to master, it will get back some new config. But the FSTableDescriptors
has been initialed so it's root dir didn't changed.
> {code}
> if (LOG.isDebugEnabled()) {
>     LOG.info("Config from master: " + key + "=" + value);
> }
> {code} 
> I thought FSTableDescriptors need update the rootdir when regionserver get report from
master.
> The master branch has same problem, too. But the balancer always assign hbase:namesapce
region to master. So this unit test can passed on master branch.
