原因分析：hadoop-dependencies/hadoop-client/2.3.0下的依赖包jackson-core-asl-1.9.13.jar、jackson-mapper-asl-1.9.13.jar和lib下的依赖包冲突引起的

解决办法：删除掉lib下的jackson-core-asl-1.9.13.jar和jackson-mapper-asl-1.9.13.jar依赖包，把hadoop-dependencies/hadoop-client/2.3.0下这两个依赖包copy过去即可。

**二、问题描述**

查询数据得不到结果？？？

解决办法：加载数据要加载到overload节点，查询数据要从broker节点查询。
