             Summary: YARN service api can not reuse json file serialized in hdfs
                 Key: YARN-7100
                 URL: https://issues.apache.org/jira/browse/YARN-7100
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn-native-services
    Affects Versions: 3.0.0-beta1
            Reporter: Eric Yang


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:

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

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.
