I know the cache operation can cache data in memoyr/disk...
But I am expecting to know will other operation will do the same?
For example, I created a dataframe called df. The df is big so when I run
some action like :
df.sort(column_name).show()
df.collect()
It will throw error like :
16/05/17 10:53:36 ERROR Executor: Managed memory leak detected; size =
2359296 bytes, TID = 15
16/05/17 10:53:36 ERROR Executor: Exception in task 0.0 in stage 12.0
(TID
15)

I want to know is there any way or configuration to let spark swap memory
into disk for this situation？
