Till Rohrmann commented on FLINK-10703:
---------------------------------------
I think all accesses to {{numPendingContainerRequests}} happen from within the
{{RpcEndpoint's}} main thread. Thus, there should be no need to make this field
atomic. Do you see any concurrent accesses [~dangdangdang]?
> Race condition in YarnResourceManager
