我编译了最新的springxd,因为我需要cdh支持。我可以启动服务器,但是当我通过xd shell连接到服务器时,我尝试更改“配置”。另外,这是一个kerberized集群,我不确定xd将/能够如何处理它。
第一种情况:
管理配置服务器--uri http:// testdomain :10111
hadoop config fs—名称节点hdfs://nameservice1:8020
hadoop config props set hadoop.security.group.mapping=org.apache.hadoop.security.shellbasedunixgroupsmapping
hadoop config props加载hadoop.security.group.mapping
hadoop fs ls软件

错误消息:

xd:>hadoop fs ls

第二种情况
或者我删除一些java选项
从上一个场景运行步骤1、2
那么
hadoop config props set hadoop.security.authorization=true
hadoop config props set hadoop.security.authentication=kerberos
以下错误
16:50:29682警告Spring壳util.nativecodeloader:62 - 无法为您的平台加载本机hadoop库。。。在适用的情况下使用内置java类ls:authorization(hadoop.security.authorization)已启用,但身份验证(hadoop.security.authorization)配置为简单。请配置其他方法,如kerberos或digest。
感谢您的帮助-迫不及待地想让这个工作!

xd中目前没有针对安全hadoop集群运行的特定支持。
欢迎随时在https://jira.springsource.org/browse/xd --我们知道这件事很快就会解决。

感谢您提出这个问题-我们已经有一段时间没有在shell中使用授权/身份验证进行测试了-尽管它是作为项目的一部分进行测试的https://github.com/vmware-serengeti/serengeti-ws
您是否能够使用标准hadoop文件系统shell执行操作。例如
hdfs dfs-ls/user/hadoop/file1
