      Description

      When YARN responds with or accepts JSON, numbers & booleans are being represented as strings which can cause parsing problems.

      Resource values look like

      {
      "application-id":"application_1404198295326_0001",
      "maximum-resource-capability":

      { "memory":"8192", "vCores":"32" }

      }

      Instead of

      {
      "application-id":"application_1404198295326_0001",
      "maximum-resource-capability":

      { "memory":8192, "vCores":32 }

      }

      When I POST to start a job, numeric values are represented as numbers:

      "local-resources":
      {
      "entry":
      [
      {
      "key":"AppMaster.jar",
      "value":

      { "resource":"hdfs://hdfs-namenode:9000/user/testuser/DistributedShell/demo-app/AppMaster.jar", "type":"FILE", "visibility":"APPLICATION", "size": "43004", "timestamp": "1405452071209" }

      }
      ]
      },

      Instead of

      "local-resources":
      {
      "entry":
      [
      {
      "key":"AppMaster.jar",
      "value":

      { "resource":"hdfs://hdfs-namenode:9000/user/testuser/DistributedShell/demo-app/AppMaster.jar", "type":"FILE", "visibility":"APPLICATION", "size": 43004, "timestamp": 1405452071209 }

      }
      ]
      },

      Similarly, Boolean values are also represented as strings:

      "keep-containers-across-application-attempts":"false"

      Instead of

      "keep-containers-across-application-attempts":false
