{code}
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.
