> On a cluster with about 500 nodes, we've seen the memory consumption goes over 12GB. This is not optimal. Using http://yunikorn.apache.org/docs/next/performance/profiling#memory-profiling, we got the memory footprint dump as attached in the JIRA. We need to optimize resource consumption and reduce the memory usage.
