我在Centos 7机器上安装了：
spark version 2.2.0
scala版本2.11.8
java version 1.8.0.0_144
Cassandra 3.11.0
所以下一步是配置spark以通过 Spark Cassandra Connector 使用cassandra，当我尝试运行时问题
$SPARK_HOME/bin/spark-shell --packages datastax:spark-cassandra-connector:2.0.3-s_2.11
请注意我也试过了这个：
$SPARK_HOME/bin/spark-shell --packages com.datastax.spark:spark-cassandra-connector_2.10:2.0.3
我得到了：

我做错了什么？我注意到那些我正在使用的版本（对于scala，spark和cassandra）没有出现在这里的兼容性版本中spark-cassandra-connector github website
