Class RSGroupInfoManagerImpl.ServerEventsListenerThread

java.lang.Object

java.lang.Thread

org.apache.hadoop.hbase.rsgroup.RSGroupInfoManagerImpl.ServerEventsListenerThread

All Implemented Interfaces:

Runnable, ServerListener

Enclosing class:

RSGroupInfoManagerImpl

private class RSGroupInfoManagerImpl.ServerEventsListenerThread
extends Thread
implements ServerListener

Calls RSGroupInfoManagerImpl.updateDefaultServers(SortedSet) to update list of known servers. Notifications about server changes are received by registering ServerListener. As a listener, we need to return immediately, so the real work of updating the servers is done asynchronously in this thread.
