我编译了最新的spring-xd,因为我需要CDH支持。我能够启动服务器但是当我通过xd-shell连接到服务器时,我尝试更改“配置”。这也是一个kerberized集群,我不知道xd将如何/可以处理它。
第一种情况:

第二种情况
或者我删除了一些java opts
运行上一个场景中的步骤1,2
然后
错误
16:50:29,682 WARN Spring Shell util.NativeCodeLoader:62 - 无法为您的平台加载native-hadoop库...使用适用的builtin-java类 ls:启用了授权(hadoop.security.authorization),但身份验证(hadoop.security.authentication)配置为简单。请配置其他方法,如kerberos或digest。
感谢您的帮助 - 迫不及待地想要让它发挥作用!
答案 0 :(得分:0)
目前,XD中没有针对安全Hadoop集群运行的特定支持。
随时在https://jira.springsource.org/browse/XD打开JIRA门票 - 这是我们知道的,我们很快就要解决这个问题。
答案 1 :(得分:0)
感谢您提出这一点 - 我们尚未在shell中使用授权/身份验证进行测试一段时间 - 尽管它已作为项目的一部分进行测试https://github.com/vmware-serengeti/serengeti-ws
您是否能够使用标准的hadoop文件系统shell执行操作。 e.g。
hdfs dfs -ls / user / hadoop / file1
