HBaseClientService unable to connect when Phoenix is installed
Nifi使用PutHbaseJSON往HDP平臺的HBASE裏面寫入數據時，HBase_1_1_2_ClientService enable之後，雖然顯示已經Enabling，但日誌提示Controller Service disabled ，報如下錯誤：

原因：
找不到類org.apache.hadoop.hbase.ipc.controller.ServerRpcControllerFactory，此類爲phoenix下的類，需要將phoenix-$version-client.jar放到classpath路徑下面。
解決辦法：
1.通過AMBARI關閉Phoenix開關，此時HBase_1_1_2_ClientService不再需要Phoenix相關的類。
2.通過AMBARI安裝Phoenix query server，將Phoenix的phoenix-$version-client.jar拷貝到nifi的work/nar/下面，在Controller Service的HBase_1_1_2_ClientService中classpath選項中指定此JAR包路徑。
