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

             Summary: Fix question 101 [Optimize code]
                 Key: TUBEMQ-102
                 URL: https://issues.apache.org/jira/browse/TUBEMQ-102
             Project: Apache TubeMQ
          Issue Type: Bug
            Reporter: viviel
            Assignee: 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}
