Jimmy Xiang commented on HBASE-6272:
One of the example is:
{code}
void regionOnline(HRegionInfo regionInfo, ServerName sn) {
// no lock concurrency ok.
this.regionsInTransition.remove(regionInfo.getEncodedName());
synchronized (this.regions) {
// Add check
ServerName oldSn = this.regions.get(regionInfo);
if (oldSn != null) LOG.warn(Overwriting + regionInfo.getEncodedName() +
on + oldSn + with + sn);
if (isServerOnline(sn)) {
this.regions.put(regionInfo, sn);
addToServers(sn, regionInfo);
this.regions.notifyAll();
} else {
LOG.info(The server is not in online servers, ServerName= +
sn.getServerName() + , region= + regionInfo.getEncodedName());
}
}
{code}
If the server is not online any more, it is not in transition, nor online.

Project: HBase
Issue Type: Bug
Reporter: Jimmy Xiang
Assignee: Jimmy Xiang
AssignmentManger stores region state related information in several places:
regionsInTransition, regions (region info to server name map), and servers
(server name to region info set map). However the access to these places is
not coordinated properly. It leads to inconsistent in-memory region state
information. Sometimes, some region could even be offline, and not in
transition.
