> 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
