Sean Owen 34b7c35380 SPARK-4682 [CORE] Consolidate various 'Clock' classes ... Another one from JoshRosen 's wish list. The first commit is much smaller and removes 2 of the 4 Clock classes. The second is much larger, necessary for consolidating the streaming one. I put together implementations in the way that seemed simplest. Almost all the change is standardizing class and method names. Author: Sean Owen <sowen@cloudera.com> Closes #4514 from srowen/SPARK-4682 and squashes the following commits: 5ed3a03 [Sean Owen] Javadoc Clock classes; make ManualClock private[spark] 169dd13 [Sean Owen] Add support for legacy org.apache.spark.streaming clock class names 277785a [Sean Owen] Reduce the net change in this patch by reversing some unnecessary syntax changes along the way b5e53df [Sean Owen] FakeClock -> ManualClock; getTime() -> getTimeMillis() 160863a [Sean Owen] Consolidate Streaming Clock class into common util Clock 7c956b2 [Sean Owen] Consolidate Clocks except for Streaming Clock		2015-02-19 15:35:23 -08:00
