尝试通过Sqoop2向Hbase中import数据过程报错

各位好，这两天部署了一套3节点的CDH集群做测试，尝试使用Sqoop2从Mysql向Hbase中导入数据，过程中遇到了报错，尝试解决未果，请各位帮忙看一下是否有解决思路。

环境：
Centos 6.5 64bit
Cloudera Manager 5.4
CDH 5.3.3

CDH中的相关组件版本为:
Sqoop2 1.99.4
hbase 0.98.6
hadoop 2.5.0

Hbase的JDBC Driver使用的是phoenix-4.3.1。
现在create link & job 都已经通过了，但是start job时报错：

java.lang.IllegalAccessError: class com.google.protobuf.HBaseZeroCopyByteString cannot access its superclass com.google.protobuf.LiteralByteString

按照这篇文章（http://my.oschina.net/cloudcoder/blog/291486）里面的说明，已经把hbase-protocol-0.98.6-cdh5.3.3.jar & hbase-protocol.jar 通过ln建立连接到了下面两个目录，重启整个CDH集群后，仍然报错。

/opt/cloudera/parcels/CDH/lib/hadoop/

/opt/cloudera/parcels/CDH/lib/hadoop/lib

下面是供参考的建立link & job的过程和完整报错：

建立Link(下面是建立hbase link的过程，建立mysql的link过程略)：
