farmmamba updated HDFS-17567:
-----------------------------
Description:
Below code is the return value in method RouterRpcClient#invokeSequential.
{code:java}
// Return the first result, whether it is the value or not
@SuppressWarnings("unchecked") T ret = (T) firstResult;
return new RemoteResult<>(locations.get(0), ret); {code}
`locations.get(0)` is not accurate, because it may not be the remote location
where ret was returned.
> Return value of method RouterRpcClient#invokeSequential is not accurate
