Bharath Vissapragada updated HBASE-26021:
-
Release Note: Incompatible table metadata serialization that was added to 
1.7.0 is undone by this change. This faulty serialization causes upgrade issues 
from pre-1.7.0 versions to 1.7.0/2.x. Release 1.7.0 will be withdrawn from 
mirrors and the suggested upgrade version is 1.7.1+.

Description: 
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*"
