Sunil G commented on YARN-4925:
-------------------------------
Thanks [~Naganarasimha Garla] for the clarification. One final doubt, in this
case if we change the labelExpression for ANY containerRequest , it will
replace the expression set by node/rack local earlier. Correct.
> ContainerRequest in AMRMClient, application should be able to specify
> nodes/racks together with nodeLabelExpression

> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Bibin A Chundatt
> Assignee: Bibin A Chundatt
>
> Currently with nodelabel AMRMClient will not be able to specify nodelabels
> with Node/Rack requests.For application like spark NODE_LOCAL requests cannot
> be asked with label expression.
> As per the check in {{AMRMClientImpl#checkNodeLabelExpression}}
> {noformat}
> // Don't allow specify node label against ANY request
> if ((containerRequest.getRacks() != null &&
> (!containerRequest.getRacks().isEmpty()))
> ||
> (containerRequest.getNodes() != null &&
> (!containerRequest.getNodes().isEmpty()))) {
> throw new InvalidContainerRequestException(
> "Cannot specify node label with rack and node");
> }
> {noformat}
> {{AppSchedulingInfo#updateResourceRequests}} we do reset of labels to that of
> OFF-SWITCH.
> The above check is not required for ContainerRequest ask /cc [~wangda] thank
> you for confirming
