Jonathan Turner Eagles commented on TEZ-4155:
---------------------------------------------
Not sure this implementation is correct. Now conf will be initialized upon
first class reference with a new TezConfiguration not based on runtime
configuration. Next first call to setConfiguration will pass runtime
configuration, but it won't be null so it will be discarded as reset isn't
called.
> Remove sync bottleneck in counters
