Description

The Drill query Cancel functionality does not log the origin of the Cancel request.

(1). security issue, we don't know who (which user) canceled the query.

(2). debugging such a canceled query can be a pain to find the origin and the root cause of why a query was canceled.

On Apache Drill 1.14.0 git.commit.id.abbrev=b0314a3, we have observed this problem, and it can be consistently reproduced. There is no information at all about the origin of why the query was canceled in the drillbit.log
