YARN API ResourceUtils's getRequestedResourcesFromConfig doesn't recognize yarn.io/gpu as a valid resource

      Description

      The original issue was the jobclient test did not send the requested resource type, when specified in the command line eg:

      hadoop jar hadoop-mapreduce-client-jobclient-tests.jar sleep -Dmapreduce.reduce.resource.yarn.io/gpu=1  -m 10 -r 1 -mt 90000
      

      After some investigation, it turned out it only affects resource types with name containing '.' characters. And the root cause is regexp from the getRequestedResourcesFromConfig method.

      "^" + Pattern.quote(prefix) + "[^.]+$"
      

      This regexp explicitly forbids any dots in the resource type name, which is inconsistent with the default resource type for gpu and fpga, which are yarn.io/gpu and yarn.io/fpga respectively.
