Sangjin Lee commented on YARN-4447:
-----------------------------------
bq. IMO, we cannot lowercase the whole expression as
events/metrics/configs,etc.in filters have to be matched as-is. Thoughts ?
Per previous comment, I'm fine with that.
bq. Thanks for the pointer. Yes, synchronization is not required here, so
ArrayDeque can be used here.
The only reason I suggested {{LinkedList}} is because we don't know the size of
the stack/deque in advance, right? API-wise, both should be completely
identical (i.e. you should be able to use {{pop}} and {{push}} like a stack).
