求助帖：spark+phoenix数据写入

测试环境：hadoop-2.2，phoenix-4.4.0，hbase-0.98.12.1，spark-1.4.1
测试内容：运用phoenix的spark组件向hbase中写入RDDs
异常问题：java.sql.SQLException: java.lang.IllegalAccessError: class com.google.protobuf.HBaseZeroCopyByteString cannot access its superclass com.google.protobuf.LiteralByteString
尝试解决：hbase的一个BUG，如http://www.aboutyun.com/forum.php?mod=viewthread&tid=9464所述。尝试添加hbase-protocol-0.98.12.1-hadoop2.jar在spark-submit --jars 之后，无效；尝试
$ HADOOP_CLASSPATH=/path/to/hbase-protocol.jar:/path/to/hbase/conf hadoop jar MyJob.jar MyJobMainClass$ HADOOP_CLASSPATH=$(hbase mapredcp):/path/to/hbase/conf hadoop jar MyJob.jar MyJobMainClass
$ HADOOP_CLASSPATH=$(hbase classpath) hadoop jar MyJob.jar MyJobMainClass
报错：Exception in thread "main" java.lang.NoClassDefFoundError: scala/collection/Seq

求指教！
