Siddharth Seth commented on TEZ-3105:
-------------------------------------
Missed that. [~rajesh.balamohan], [~gopalv] - thoughts on the performance
implications of such a change ?
One possible option would be to include the IBM OSMXBean based class under a
separate profile which does not get built by default. It lives in the source,
but gets compiled only when using the IBM JDK. Similarly an option to disable
the compilation of the com.sun based implementation. The usage would end up
creating the appropriate instance via Reflection.
