HBase shaded client 1.1.x on Cloudera 5.4.7 (HBase 1.0.0)

["zhengshencn@outlook.com" <zh...@outlook.com>]

Hi all,

Is there any known issues to use HBase client library from latter release on HBase server in a relatively old release?

I'm running into a trouble recently when trying to create an Java based client which is used to query data from both Cloudera HBase 1.0.0 (CDH 5.4.7) and ElasticSearch 2.1.0. The issue is about dependency conflicts on guava library, which exactly like this one https://issues.apache.org/jira/browse/HBASE-14126.

As a workaround, I'm using the Apache HBase Shaded Client 1.1.2 library (which is designed for HBase 1.1.0 I suppose) with Cloudera HBase 1.0.0 (CDH 5.4.7) . So far I haven't met any issue yet. 

However I still want to check if there is any known issues already on this combination (client & server), so is there any common sense in HBase/Hadoop world around using different versions of server/client in a production environment. 

Thanks!

All 1.x client and servers should be compatible by design. If the server
side is based on 1.0 and client side is 1.1, it should work as expected.
Otherwise, it is a bug.
