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.
