             Summary: LLAP: Add some additional jvm metrics for hadoop-metrics2 
                 Key: HIVE-16072
                 URL: https://issues.apache.org/jira/browse/HIVE-16072
             Project: Hive
          Issue Type: Bug
          Components: llap
    Affects Versions: 2.2.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran


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.
