This is what I would recommend as the least bad option (all options are bad...)
# Withdraw the 1.7.0 release immediately. Delete from the mirrors.
# Apply the fix. I like your simple fix posted on this issue above [~vjasani]
but since we backported a change it makes more sense to backport its revert
too:
[commit|https://github.com/apache/hbase/commit/bdb0cc8808af7c3d08af4a506f34b8341726b58e]
# Release 1.7.0.1.
The vote and review of the 1.7.0.1 RC should be fast given there have been few
commits since 1.7.0.
When we release 1.7.0.1 we can state in the release notes that 1.7.0 had this
bug and anyone who upgraded to it who wants to upgrade to 2.x must upgrade to
1.7.0.1 first.

> As of today, if we bring up HBase cluster using branch-1 and upgrade to
> branch-2.4, we are facing issue while parsing namespace from HDFS fileinfo.
> Instead of "*hbase:meta*" and "*hbase:namespace*", parsing using ProtobufUtil
> seems to be producing "*\n hbase meta*" and "*\n hbase namespace*"
