[jira] [Updated] (HBASE-16359) NullPointerException in
RSRpcServices.openRegion()
[ https://issues.apache.org/jira/browse/HBASE-16359?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ted Yu updated HBASE-16359:
---------------------------
Description:
I was investigating why some region failed to move out of transition within timeout 120000ms and found the following in region server log:
{code}

Here is related code - NPE was thrown from the last line:

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.
