Exception in thread "main"

解决办法：

1.导入一下pom.xml

<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-protocol</artifactId>
<version>1.4.11</version>
</dependency>

如果导入后依然报错，但是报错是找不到某些方法，是导入的client和protocol不一致：如下

<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-client</artifactId>
<version>1.0.0-cdh5.4.4</version>
</dependency> <dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-protocol</artifactId>
<version>1.4.11</version>
</dependency>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.6.0</version>
</dependency>

一个1.4.11一个1.0

因此改为：
