------------------------------
Summary: NullPointerException in RSRpcServices.openRegion()

Issue Type: Bug
Reporter: Ted Yu

Here is related code - NPE was thrown from the last line:
{code}
htd = htds.get(region.getTable());
if (htd == null) {
htd = regionServer.tableDescriptors.get(region.getTable());
htds.put(region.getTable(), htd);
}
...
if (region.isMetaRegion()) {
regionServer.service.submit(new OpenMetaHandler(
regionServer, regionServer, region, htd, masterSystemTime, coordination, ord));
} else {
regionServer.updateRegionFavoredNodesMapping(region.getEncodedName(),
regionOpenInfo.getFavoredNodesList());
if (htd.getPriority() >= HConstants.ADMIN_QOS || region.getTable().isSystemTable()) {
{code}
region.getTable() shouldn't be null since it is called via htds.get(region.getTable()) unconditionally.
It seems htd was null.
