      There seems to be a race condition happening when an application is KILLED and the corresponding container event information is being published. For completed containers, a YARN_CONTAINER_FINISHED event is generated but for some containers in a KILLED application this information is missing. Below is a node manager log snippet,

      The container id specified in the log, container_1523259757659_0003_01_000002 is the one that has the finished event missing.
