troubleshooting-windows 在 CDH集群环境读取 Hive 表 KrbException: Cannot locate default realm

KrbException: Cannot locate default realm

 

解决办法

1）拷贝需要组件的配置文件到项目中的 /resources/目录。如hadoop，目录/etc/hadoop/conf/

2）代码中写入如下代码

System.setProperty("java.security.krb5.conf", "D:\\work\\conf\\krb5.conf")
System.setProperty("HADOOP_USER_NAME", "chenweidong")
System.setProperty("user.name", "chenweidong");
UserGroupInformation.loginUserFromKeytab("chenweidong@HADOOP.COM", "D:\\work\\conf\\cwd.keytab")
System.out.println(UserGroupInformation.getLoginUser())
