Doug Haigh commented on YARN-2546:
----------------------------------
The definition of the fields does not match the JSON returned. This is a
problem for non-Java parsers. Not an insurmountable problem, but a problem.
> REST API for application creation/submission is using strings for numeric &
> boolean values

> Key: YARN-2546
> URL: https://issues.apache.org/jira/browse/YARN-2546
> Project: Hadoop YARN
> Issue Type: Bug
> Components: api
> Affects Versions: 2.5.1
> Reporter: Doug Haigh
>
> 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
