> It will be helpful for debugging to expose some metrics like buffer pool, file descriptors etc. that are not exposed via Hadoop's JvmMetrics. We already a /jmx endpoint that gives out these info but we don't know the timestamp of allocations, number file descriptors to correlated with the logs. This will better suited for graphing tools.
