    Description

      This is part of the work for SENTRY-1760.

      A new DB definition is already created that contains a generation ID for new HMS snapshots (SENTRY-1805). This new generation ID is persisted and code is implemented to read and update paths with a current generation ID (SENTRY-1781).

      This patch will these new HMS snapshots to HDFS whenever HDFS requests an old generation ID.
