SPARK-1299: making comments of RDD.doCheckpoint consistent with its usage
another trivial thing I found occasionally, the comments of consistent is
saying that
/**
Performs the checkpointing of this RDD by saving this. It is called by the
DAGScheduler
after a job using this RDD has completed (therefore the RDD has been
materialized and
potentially stored in memory). doCheckpoint() is called recursively on the
parent RDDs.
*/
actually this function is called in SparkContext.runJob
we can either change the comments or call it in DAGScheduler, I personally
prefer the later one, as this calling seems like an auto-checkpoint , better
put it in a non-user-facing component
