Hi I use HDP 2.4.0, CentOS 6.7, jdk1.8.0_72 I suspect timeline server memory leak. I filed jira(https://issues.apache.org/jira/browse/YARN-5368) Because I use HDP, so I post here. I set -Xmx1024m, but ps command shows 3.5GB of memory usage. And then memory usage increases everyday. I'm wondering. What is the reason? for example, LevelDB JNI memory leak? If there is a good metrics for monitoring, could you tell me? # ps aux | grep timelineserver yarn 6163 2.7 5.3 6630548 3545856 ?
