Steve Loughran commented on HADOOP-16776:
-----------------------------------------
bq. do you thing we may want to use MonotonicClock to avoid other collision
issues?
maybe. It's only monotonic for a single core on a single socket; multicore
single socket it may be shared or private, multisocket: no guarantees at all.
But we don't want to measure things, just have different values, don't we? And
monotonic will give us more granulariy so less risk of collision.
