> 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.
