Daryn Sharp updated HDFS-8867:
    Attachment: HDFS-8867.patch

Yes, the enum is lazy initialized so it wasn't advertised.  Here's the patch we've been using
internally to force a static init.

> Opening this ticket on behalf of [~daryn]
> 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.
