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
