Lantao Jin commented on YARN-6280: ---------------------------------- I checked the report of findbugs and seems none of the listed items related to my patch... > Add a query parameter in ResourceManager Cluster Applications REST API to > control whether or not returns ResourceRequest > ------------------------------------------------------------------------------------------------------------------------ > > 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, > YARN-6280.003.patch, YARN-6280.004.patch, YARN-6280.005.patch, > YARN-6280.006.patch, YARN-6280.007.patch, YARN-6280.008.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. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
