> Project: Apache TubeMQ

> Reporter: viviel

> Because the core module uses jdk1.7, this code cannot use 'putIfAbsent'
> {code:java}
> addrMap4Failover.putIfAbsent(tmpNodeAddrInfo.getHostPortStr(),
> tmpNodeAddrInfo);
> {code}
> We should use the original
> {code:java}
> if (addrMap4Failover.get(tmpNodeAddrInfo.getHostPortStr()) == null) {
> addrMap4Failover.put(tmpNodeAddrInfo.getHostPortStr(), tmpNodeAddrInfo);
> }
> {code}
