Subject [jira] [Created] (HBASE-13318) RpcServer.Listener.getAddress should be synchronized
Date Tue, 24 Mar 2015 01:14:52 GMT
Lars Hofhansl created HBASE-13318:

             Summary: RpcServer.Listener.getAddress should be synchronized
                 Key: HBASE-13318
                 URL: https://issues.apache.org/jira/browse/HBASE-13318
             Project: HBase
          Issue Type: Bug
    Affects Versions:
            Reporter: Lars Hofhansl
            Priority: Minor

We just saw exceptions like these:
Exception in thread "B.DefaultRpcServer.handler=45,queue=0,port=60020" java.lang.NullPointerException
	at org.apache.hadoop.hbase.ipc.RpcServer$Listener.getAddress(RpcServer.java:753)
	at org.apache.hadoop.hbase.ipc.RpcServer.getListenerAddress(RpcServer.java:2157)
	at org.apache.hadoop.hbase.ipc.CallRunner.run(CallRunner.java:146)
	at org.apache.hadoop.hbase.ipc.RpcExecutor.consumerLoop(RpcExecutor.java:130)
	at org.apache.hadoop.hbase.ipc.RpcExecutor$1.run(RpcExecutor.java:107)
	at java.lang.Thread.run(Thread.java:745)

Looks like RpcServer$Listener.getAddress should be synchronized (acceptChannel is set to null
upon exiting the thread under in a synchronized block).

Should be happening very rarely only.
