    Description

      Introducing MDC logging over on HBASE-27762, we noticed an annoyance when writing a patter to ship by default. When the MDC contains no keys, %notEmpty still considers it as non-empty and renders as "{}". I expected that notEmpty would consider the absence of any keys in the MDC as an empty object.
