Spill occurs as a result of executing various wide transformations. However, diagnosing a spill requires one to proactively look for key indicators.

Where in the Spark UI are two of the primary indicators that a partition is spilling to disk?

a-   Executor's detail screen and Executor's log files

b-   Driver's and Executor's log files

c-   Stage's detail screen and Query's detail screen

d-   Query's detail screen and Job's detail screen

e-  Stage's detail screen and Executor's log files
