Benjamin Teke commented on YARN-10840:
--------------------------------------
[~abhinaba.sarkar] can you please explain this issue a bit? When/how does this
issue happen? Is there a way to reproduce it? I'm asking because depending on
the context changing the containerList's implementation to one that properly
supports concurrent access may be a cleaner solution.
