配置文件的加载是一个难点，在local模式下非常容易，但是submit后一直报找不到文件，后来采用将properties文件放在加载类同一个package下，打包到同一个jar中解决。

追踪ClientRpcControllerFactory这个类，将会发现是phoenix-core-4.4.0-HBase-1.0.jar中的，根据报错信息，可以知道也确实HBase的连接出现问题，于是我第一步去找是否将phoenix-core-4.4.0-HBase-1.0.jar这个包拷贝到Spark Client下，有的，
第二，我去找自己的spark-submit jars命令中是否对该包的引用有误，比如路径、逗号符号等，错误依然不在此。嗯！ 放弃思考，已超出自己的理解范围了，马上在stackoverflow上找到这个原生Bug
I had have same problem. The reason of problem,Phoenix use a custom rpc controller factory which is a Phoenix-specific one to configure the priorities for index and system catalog table in cluster side. It is called ClientRpcControllerFactory. In sometimes 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. That's why you get this exception. This problem is fixed by HBASE-14960. If you hbase version older than 2.0.0, 1.2.0, 1.3.0, 0.98.17 You can define your client side rpc controller with this setting in hbase-site.xml: <property>
<name>hbase.rpc.controllerfactory.class</name>
<value>org.apache.hadoop.hbase.ipc.RpcControllerFactory</value>
</property>
