Vsevolod Ostapenko commented on HBASE-14960:
--------------------------------------------
Hortonworks still ships HBase 1.1.2 in the most recent HDP 2.5 releases. Is it
possible to have a patch for this issue on 1.1.2?
> Fallback to using default RPCControllerFactory if class cannot be loaded

> In Phoenix + HBase clusters, the hbase-site.xml configuration will point to a
> custom rpc controller factory which is a Phoenix-specific one to configure
> the priorities for index and system catalog table.
> However, sometimes these Phoenix-enabled clusters are used from pure-HBase
> client applications resulting in ClassNotFoundExceptions in application code
> or MapReduce jobs. Since hbase configuration is shared between
> Phoenix-clients and HBase clients, having different configurations at the
> client side is hard.
> We can instead try to load up the RPCControllerFactory from conf, and if not
> found, fallback to the default one (in case this is a pure HBase client). In
> case Phoenix is already in the classpath, it will work as usual.
> This does not affect the rpc scheduler factory since it is only used at the
> server side.
