如何修复Hadoop警告:Ubuntu上发生了非法的反射访问操作错误
我已经安装了Java并成功了。所有进程运行良好openjdk version "10.0.2"
Hadoop 2.9.0
hadoopusr@amalendu:~$ jps
19888 NameNode
20388 DataNode
20898 NodeManager
20343 SecondaryNameNode
20539 ResourceManager
21118 Jps
但是,当我尝试执行任何命令时,例如收到此警告hdfs dfs -ls /
hadoopusr@amalendu:~$ hdfs dfs -ls /
