-----------------------------

             Summary: Possible invalid iterator in ServerManager#processQueuedDeadServers()
                 Key: HBASE-9358
                 URL: https://issues.apache.org/jira/browse/HBASE-9358
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu


serverIterator is used this way:
{code}
    Iterator<ServerName> serverIterator = queuedDeadServers.iterator();
    while (serverIterator.hasNext()) {
      ServerName tmpServerName = serverIterator.next();
      expireServer(tmpServerName);
      serverIterator.remove();
{code}
expireServer() modifies Iterable "this.queuedDeadServers" which invalidates iterator "serverIterator"
Call to remove() is applied on invalid iterator "serverIterator"
