-----------------------------
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}
