      Description

      HDFS-8432 introduced the concept of a minimum compatible layout version so that downgrade is applicable in a wider set of circumstances. This includes logic for determining if the current layout version in storage is within the bounds of the minimum compatible layout version. There is an inverted comparison in this logic, which can result in an incorrect calculation.
