Subject spark UI storage tab
Date Wed, 11 Nov 2020 21:40:25 GMT
Hi , I have few questions as below

1. In the spark ui storage tab is displayed 'storage level',' size in
memory' and size on disk, i am not sure it displays RDD ID 16 with memory
usage 76 MB not sure why it is not getting 0 once a request for spark
streaming is completed. I am caching some RDD inside a method and uncaching

2. Similarly on Executor tab it display  'Storage Memory' used and
available, is that used means currently in use  or memory used on that
executor at some point of time (maximum memory used so far)
