Java 运行HBase 例子报错?报错

爱吃鱼的程序员 2020-06-08 14:19:17 44

请问Java连接HBase报这个错怎么解决:

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.hadoop.security.authentication.util.KerberosUtil.hasKerberosTicket(Ljavax/security/auth/Subject;)Z
 

详细描述:

服务器环境:位于Ubuntu-16.04,Hadoop-2.8.0 HA集群,HBase-1.2.5 

开发环境:Win7 64位,jar 都已经导入

代码:

谢谢!

补充:如果编译成jar包到Hadoop 集群上去执行也报错:

    没设置HADOOP_HOME?

    hadoop/hbase集群上的环境都设置好了,需要在本地开发环境设置吗?

    你要把你的jar包放到hadoop集群上去执行,才能读取到hadoop的那几个xml配置文件,找到hadoop节点

    jar去重后仍报错,Causedby:java.lang.ClassNotFoundException:org.apache.htrace.Tracehtrace-core-3.0.4.jar包已经导入jar包都去重了,然后还是报错:10:13:36.584DEBUGorg.apache.zookeeper.ClientCnxn102<clinit>-zookeeper.disableAutoWatchResetisfalsejava.io.IOException:java.lang.reflect.InvocationTargetExceptionatorg.回复 @驛路梨花醉美:NoSuchMethod通常是你混合了多个版本的jar包,你检查下你的项目依赖放到hadoop集群上执行,还是报错:Causedby:java.lang.NoSuchMethodError:org.apache.hadoop.security.authentication.util.KerberosUtil.hasKerberosTicket(Ljavax/security/auth/Subject;)Z
