使用HBase客戶端Java API連接HBase集羣的時候，報異常如下：
Exception in thread "main" org.apache.hadoop.hbase.DoNotRetryIOException: java.lang.NoSuchMethodError: org.apache.hadoop.net.NetUtils.getInputStream(Ljava/net/Socket;)Lorg/apache/hadoop/net/SocketInputWrapper;

異常信息表明，NetUtils該類，缺少getInputStream(Ljava/net/Socket;)該方法，原因很可能是HBase客戶端版本與Hadoop客戶端版本不一致導致的。
解決辦法：修改Pom.xml文件，修改HBase客戶端版本與Hadoop客戶端版本，使他們兼容即可。
解決之後的Pom.xml相關配置如下：
