Hadoop启用简单身份验证
[英]Hadoop enable simple authentication
问题描述
I tried the steps listed here How to disable Hadoop Kerberos but my datanode wouldn't start because of this exception 
我尝试了此处列出的步骤如何禁用Hadoop Kerberos，但由于此异常，我的datanode无法启动
java.lang.IllegalArgumentException: Does not contain a valid host:port authority: 50010
at org.apache.hadoop.net.NetUtils.createSocketAddr(NetUtils.java:212)

I have apache hadoop 2.6 installed on a CentOS vm. 我在CentOS vm上安装了apache hadoop 2.6。 I started hadoop with start-dfs.sh and start-yarn.sh . 我从start-dfs.sh和start-yarn.sh开始hadoop。 I'm trying to connect to hadoop from a java client with hdfs protocol but I am getting the below exception. 我正在尝试使用hdfs协议从Java客户端连接到hadoop，但出现以下异常。
Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): SIMPLE authentication is not enabled. Available:[TOKEN]
at org.apache.hadoop.ipc.Client.call(Client.java:1468)
at org.apache.hadoop.ipc.Client.call(Client.java:1399)
at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:232)
I've seen a similar exception posted a few times by other people but it usually ends in [TOKEN, KERBEROS] . 我见过几次其他人发布的类似异常，但通常以[TOKEN, KERBEROS]结尾。 Do I need to enable KERBEROS authentication or is TOKEN something else? 我需要启用KERBEROS身份验证还是令牌其他东西？ Ideally I would like to just use simple authentication. 理想情况下，我只想使用简单身份验证。 If I can't use simple authentication would installing CDH4 satisfy the TOKEN authentication? 如果我不能使用简单身份验证，安装CDH4是否可以满足TOKEN身份验证？

问题是我将请求发送到从本地主机：8088获得的节点地址端口，而不是端口8020或core-site.xml中fs.defaultFS中指定的任何端口。
