> Add profiler endpoint to HS2 and LLAP
> -------------------------------------

> Key: HIVE-20202
> URL: https://issues.apache.org/jira/browse/HIVE-20202
> Project: Hive
> Issue Type: New Feature
> Affects Versions: 4.0.0, 3.2.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Major
> Attachments: HIVE-20202.1.patch, HIVE-20202.2.patch,

>
>
> Add a web endpoint for profiling based on async-profiler. This servlet should
> be added to httpserver so that HS2 and LLAP daemons can output flamegraphs
> when their /prof endpoint is hit. Since this will be based on
> [https://github.com/jvm-profiling-tools/async-profiler] heap allocation, lock
> contentions, HW counters etc. will also be supported in addition to cpu
> profiling. In most cases the profiling overhead is pretty low and is safe to
> run on production. More analysis on CPU and memory overhead here
> [https://github.com/jvm-profiling-tools/async-profiler/issues/14] and
> [https://github.com/jvm-profiling-tools/async-profiler/issues/131]
>
> For the impatient, here is the usage doc and the sample output
> [https://github.com/prasanthj/nightswatch/blob/master/README.md]
