Description

org.apache.hadoop.yarn.service.api.records.Resource has a new method introduced in YARN-6903 for casting memory from string to long value. However, the method name getMemoryMB introduces new output in json that looks like this:

    "resource" : {
      "uri" : null,
      "profile" : null,
      "cpus" : 1,
      "memory" : "2048",
      "memory_mb" : 2048
    },

This prevents the file to be resubmitted to services api because memory_mb property is unknown to the REST API. It may be better to rename getMemoryMB method to calcMemoryMB to avoid the method to be serialized unintentionally.
