我已经在docker中部署了hadoop，docker在AWSEC2 UbuntuAMI示例上运行。
当我试图在hdfs中创建一个目录时，它会说cannotcreatedirectory。名称节点处于安全模式
以下是hdfs-site.xml中的属性

name: dfs.replication
value: 1
name: dfs.namenode.name.dir
value: /usr/local/hadoop/data

当我检查hdfs报告时，它给出了以下输出。

bash-4.1# hdfs dfsadmin -report
19/01/05 12:34:20 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

下面是关于namenode的一些细节。

bash-4.1# hdfs dfs -df
19/01/05 12:37:20 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

hdfs://0cd4da30c603:9000     0  335872          0  Infinity%

如果我设置为离开安全模式，几秒钟之内它就会回到安全模式。

bash-4.1# hdfs dfsadmin -safemode leave
19/01/05 12:42:26 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

下面是我的文件系统信息

bash-4.1# df -h

我期望的是在hdfs中创建一个目录来执行mapreduce操作
