gaojinchao commented on HBASE-3933:
-----------------------------------
I study the TRUNK. It has fixed. So we can close this issue.
Trunk code:
// Wait for region servers to report in.
this.serverManager.waitForRegionServers(status);
// Check zk for regionservers that are up but didn't register
for (ServerName sn: this.regionServerTracker.getOnlineServers()) {
if (!this.serverManager.isServerOnline(sn)) {
// Not registered; add it.
LOG.info("Registering server found up in zk: " + sn);
this.serverManager.recordNewServer(sn, HServerLoad.EMPTY_HSERVERLOAD);
}
}
