the life cycle shuffle Dependency

[yang chen]

hi, I'm learning spark, and wonder when to delete shuffle data, I find the
ContextCleaner class which clean the shuffle data when shuffle dependency
is GC-ed.  Based on source code, the shuffle dependency is gc-ed only when
active job finish, but i'm not sure,  Could you explain the life cycle of a
Shuffle-Dependency?
