      Description

      Opening this ticket on behalf of Daryn Sharp
      HDFS-7435 introduced a more efficiently encoded block report format designed to improve performance and reduce GC load on the NN and DNs. The NN is not advertising this capability to the DNs so old-style reports are still being used.
