             Summary: Look into hbase-2 client going to hbase-1 server
                 Key: HBASE-19145
                 URL: https://issues.apache.org/jira/browse/HBASE-19145
             Project: HBase
          Issue Type: Task
    Affects Versions: 2.0.0-beta-1
            Reporter: Jerry He
            Priority: Major

>From the "[DISCUSS] hbase-2.0.0 compatibility expectations" thread.

Do we support hbase-2 client going against hbase-1 server?
We seem to be fine mix-and-match the clients and servers within the
hbase-1 releases.   And IIRC hbase-1 client is ok against 0.98 server.
Suppose I have a product  that depends and bundles HBase client. I
want to upgrade the dependency to hbase-2 so that it can take
advantages of and claim support of hbase-2.
But does it mean that I will need drop the claims that the new version
of the product support any hbase-1 backend?

It has not been an objective. It might work doing basic Client API on a
later branch-1 but will fail doing Admin functions (and figuring if a Table
is online).  If it was a small thing to make it
work, lets get it in.

Let's look into it to see what works and what not.  Have a statement at least.
