> Add a query parameter in ResourceManager Cluster Applications REST API to

> Key: YARN-6280
> URL: https://issues.apache.org/jira/browse/YARN-6280
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager, restapi
> Affects Versions: 2.7.3
> Reporter: Lantao Jin
> Assignee: Lantao Jin
> Attachments: YARN-6280.001.patch, YARN-6280.002.patch,

>
> Begin from v2.7, the ResourceManager Cluster Applications REST API returns
> ResourceRequest list. It's a very large construction in AppInfo.
> As a test, we use below URI to query only 2 results:
> http://<rm http
> address:port>/ws/v1/cluster/apps?states=running,accepted&limit=2
> The results are very different:
> ||Hadoop version|Total Character|Total Word|Total Lines|Size||
> |2.4.1|1192| 42| 42| 1.2 KB|
> |2.7.1|1222179| 48740| 48735| 1.21 MB|
> Most RESTful API requesters don't know about this after upgraded and their
> old queries may cause ResourceManager more GC consuming and slower. Even if
> they know this but have no idea to reduce the impact of ResourceManager
> except slow down their query frequency.
> The patch adding a query parameter "showResourceRequests" to help requesters
> who don't need this information to reduce the overhead. In consideration of
> compatibility of interface, the default value is true if they don't set the
> parameter, so the behaviour is the same as now.
