---------------------------------------
I did a first version of this service. I checked several requests and it was
OK. More check would be nice.
Topology:

> Apache Hadoop Timeline Server REST API support
> ----------------------------------------------
>
> Key: KNOX-1031
> URL: https://issues.apache.org/jira/browse/KNOX-1031
> Project: Apache Knox
> Issue Type: New Feature
> Components: Server
> Affects Versions: 0.13.0
> Environment: Apache Hadoop clusters, HortonWorks clusters, Cloudera
> clusters, MapR clusters
> Reporter: Pierre Beauvois
> Fix For: 0.14.0
>
>
> Timeline Server REST API as documented here: [Timeline Server REST
> API|https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/TimelineServer.html#Timeline_Server_REST_API_v1]
> The TLS REST API provides a RESTful interface to a Timeline Server. It makes
> it easy to produce and consume messages, view the state of the cluster, and
> perform administrative actions
> This feature allow to call Timeline Server REST API through Knox. It could be
> enabled in your topology by adding the following sample:
> {code:java}
> <service>
> <role>TIMELINESERVER</role>
> <url>http://{timelineserver-host}:{timelineserver-port}</url>
> </service>
> {code}
