Subject Spark job (not Spark streaming) doesn't delete un-needed checkpoints.
Date Fri, 10 Oct 2014 16:15:11 GMT
Un-needed checkpoints are not getting automatically deleted in my

I.e. the lineage looks something like this and checkpoints simply
accumulate in a temporary directory (every lineage point, however, does zip
with a globally permanent):

PermanentRDD:    Global zips with all the intermediate ones

Intermediate RDDs: A--->B--->C---->D---->E---->F---->----->G
                                |                          |
                              checkpoint          checkpoint

Older intermediate RDDs never get used.
