Any other concerns?
Thanks.

When filling the release note, I found that I'd better do some works on
master first, such as removing the deprecated methods in Table interface,
so the release note will be clean. And also I seem to forget changing the
javadoc for some methods in the Admin interface since their behavior have
been
HBASE-22577 is almost there. But I think I still need one more +1 here so I
can merge HBASE-21512 back...

After applying HBASE-22577 the performance is good enough now. And the YCSB
workloada also shows that there are no big differences on performance.
Please see the comments on HBASE-22564 for more details.
Will get HBASE-22577 in soon, and resolve the pending issues such
as HBASE-22237.

It’s hadoop-2.8.5.
But I do not think it makes much difference, we just use the same server
setup, only different clients implementation.

Duo,
What version on Hadoop did you use in the 5 node cluster for your
comparisons? For what it's worth, I would also like to try out the PE/LTT
comparison of both the clients. Or, if any other form of comparison would
be helpful then I'm open for suggestions and would like to give it a try.
It will be transparent, mostly, the interface is still kept. There are some
incompatible behaviors, for example, now admin.split will wait till the
split is actually done, while in the old time it will return immediately
after we send the request to master.

Hi,
Is this going to change the way the client should be called? Or it will be
mostly transparent replacement?
Thanks,

Nice perf results!

Let me do a YCSB test about the performance.

It removes the complicated multi-threaded edifice we'd built client-side to
fake an async behavior replacing it with an actual async implementation.
Users will immediately notice a radical plummet in working thread count on
the client side.

"Reimplement sync client based on async client"
The jira title tells everything. This is what I promised when I first
introduced the async client in HBase, about three years ago, that the sync
client can be implemented on top of the async client,
