Subject [jira] [Comment Edited] (YARN-6756) ContainerRequest#executionTypeRequest causes NPE

--------------------------------------------------------

I actually run into NPE when I use the builder API, if I caller doesn't explicitly call executionTypeRequest()
method to set a dummy object, it always throws NPE, I think we need to initialize it with
a default object

> ContainerRequest#executionTypeRequest is initialized as null, which could cause below
" execTypeReq.getExecutionType" unconditionally throw NPE.
