我正在尝试连接到kerberized hdfs群集,使用下面的代码,使用下面相同的代码,我当然可以通过hbaseconfiguration访问hbase,
Configuration config = new Configuration();
config.set("hadoop.security.authentication", "Kerberos");
UserGroupInformation.setConfiguration(config);
UserGroupInformation ugi = null;
ugi = UserGroupInformation.loginUserFromKeytabAndReturnUGI("me@EXAMPLE>COM","me.keytab");
model = ugi.doAs((PrivilegedExceptionAction<Map<String,Object>>) () -> {
testHadoop(hcb.gethDFSConfigBean());
return null;
});
我已经能够成功地使用相同的keytab和principal访问solr、impala,我得到了一个奇怪的消息:找不到hdfs的服务名。
请看下面的堆栈跟踪

我对spark2和hdp3.1也有同样的问题,使用isilon/onefs作为存储,而不是hdfs。
onefs服务管理包没有为spark2期望的某些hdfs参数提供配置(它们在ambari中根本不可用),例如dfs.datanode.kerberos.principal。如果没有这些参数,spark2 historyserver可能无法启动并报告错误,例如“指定服务器的主体名称失败”。
我在自定义hdfs站点下向onefs添加了以下属性:
这解决了最初的错误。此后,我得到了以下形式的错误:
这与跨领域身份验证有关。通过将以下设置添加到自定义hdfs站点来解决:
o3imoua42#
我认为问题是hdfs期望配置具有dfs.datanode.kerberos.principal的值,这是datanodes的主体,在本例中它是缺失的。
当我只从core-site.xml创建一个配置示例,却忘记添加hdfs-site.xml时,我也遇到了同样的问题。我一添加hdfs-site.xml它就开始工作了,hdfs-site.xml有:
希望这有帮助。
