Application timeline server is crashing

[#1]

PROBLEM: ATS crashes silently. No errors or exceptions in the logs.

ROOT CAUSE: Operating system's OOM Killer kills ATS because it uses highest memory(more memory than assigned heap)

RESOLUTION : Please add below properties in yarn-site.xml to fix this:

yarn.timeline-service.ttl-ms=604800000
yarn.timeline-service.rolling-period=daily
yarn.timeline-service.leveldb-timeline-store.read-cache-size=4194304
yarn.timeline-service.leveldb-timeline-store.write-buffer-size=4194304
yarn.timeline-service.leveldb-timeline-store.max-open-files=500
