> Key: HBASE-9358
> URL: https://issues.apache.org/jira/browse/HBASE-9358
> Project: HBase
> Issue Type: Bug
> Reporter: Ted Yu
> Priority: Trivial
>
> 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"
