I put up 0.98.25-SNAPSHOT again on one cluster and tip of branch-2 on the
other. I added respective peers on each end. The enable_table_replication
command will never succeed since it hashes the two TableDescriptors, the one on
peer and the local source, and they'll never compare, so I enabled table
replication by altering the table and setting REPLICATION_SCOPE to global scope
('1'). I then shoved edits through and they showed up on both ends promptly.
As per [~esteban], replication basically works. Lets file issues for more
explicit problems replicating across versions. Resolving for now.

Trying this, yeah, a 1.2 seems to replicate fine to a 2.x cluster. The 1.2
cluster wanted to create the remote table else I saw the below complaint:
{code}
ERROR: Table 98 exists in peer cluster 1, but the table descriptors are not
same when compared with source cluster. Thus can not enable the table's
replication switch.
{code}
I need to see more what it was objecting too.
I did not seem to be able to replicate from hbase2 to hbase1... would hang at
least on enable_table_replication. Let me see if can make it work if table
already created... maybe not given table state is not in zk.
