We're seeing a bunch of .snapshot files being created under /home/spark/Snapshots, such as the following for example:
CoarseGrainedExecutorBackend-2015-08-27-shutdown.snapshot CoarseGrainedExecutorBackend-2015-08-31-shutdown-1.snapshot SparkSubmit-2015-08-31-shutdown-1.snapshot Worker-2015-08-27-shutdown.snapshot These files are large and they blow out our disk space in some environments. What are these, when are they created and for what purpose? Is there a way to control how they're generated and most importantly where they're stored? Thanks.
