Subject Re: Profiling the internal of Hive

For Tez containers, you can specify JVM args via config
setting, there’s probably a similar setting for MR. You can add the
profiler agent to this setting, there e.g. for Yourkit something like:
etracing,dir=/tmp/ykdumps,sampling" or for JMC that is built in on some
versions of JVM something like "-XX:+UnlockCommercialFeatures
Then look at profiler dumps.
