-------------------------------------
Summary: Fallback to using default RPCControllerFactory if class
cannot be loaded
Key: HBASE-14960
URL: https://issues.apache.org/jira/browse/HBASE-14960
Project: HBase
Issue Type: Bug
Reporter: Enis Soztutar
Assignee: Enis Soztutar
Fix For: 2.0.0, 1.2.0, 1.3.0
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.
