hello using spark 2.0.2 and while running sample streaming app with kinesis noticed (in admin ui Storage tab) "Stream Blocks" for each worker keeps climbing up
then also (on same ui page) in Blocks section I see blocks such as below input-0-1484753367056 that are marked as Memory Serialized that do not seem to be "released" above eventually consumes executor memories leading to out of memory exception on some is there a way to "release" these blocks free them up , app is sample m/r I attempted rdd.unpersist(false) in the code but that did not lead to memory free up thanks much in advance!
