Andrew Purtell reopened HBASE-14771:
------------------------------------
This change will cause Phoenix's PhoenixIndexRpcSchedulerTest to fail with a
NPE. There is something very simple (and correct) we can do as an addendum to
fix it. Attaching the addendum. Unless objection will commit the addendum to
all branches that have this change shortly, to get the 0.98 RC out the door.

> RpcServer.getRemoteAddress always returns null, because Call object is
> getting initialized with null.This seems to be happening because of using
> RpcServer.getRemoteIp() in Call object constructor before RpcServer thread
> local 'CurCall' being set in CallRunner.run method:
> {noformat}
> // --- RpcServer.java ---
> protected void processRequest(byte[] buf) throws IOException,
> InterruptedException {
> .................................
> // Call object getting initialized here with address
> // obtained from RpcServer.getRemoteIp()
> Call call = new Call(id, this.service, md, header, param, cellScanner, this,
> responder,
> totalRequestSize, traceInfo, RpcServer.getRemoteIp());
> scheduler.dispatch(new CallRunner(RpcServer.this, call));
> }
> // getRemoteIp method gets address from threadlocal 'CurCall' which
> // gets set in CallRunner.run and calling it before this as in above case,
> will return null
> // --- CallRunner.java ---
> public void run() {
> .........................
> Pair<Message, CellScanner> resultPair = null;
> RpcServer.CurCall.set(call);
> ..............................
> }
> // Using 'this.addr' in place of getRemoteIp method in RpcServer.java seems
> to be fixing this issue
> Call call = new Call(id, this.service, md, header, param, cellScanner, this,
> responder,
> totalRequestSize, traceInfo, this.addr);
> {noformat}
