Eclipse遠端連線hadoop時 報 Permission denied:

標籤：des   style   color   io   re   c   

用Eclipse遠端連線hadoop時報org.apache.hadoop.security.AccessControlException: Permission denied: user=DrWho, access=READ_EXECUTE, inode="system":hadoop:supergroup:rwx-wx-wx錯誤，解決方案：

     在hdfs-site.xml 中取消許可權校正，即加入以下配置：

<property>
    <name>dfs.permissions</name>
    <value>false</value>
    <description>
       If "true", enable permission checking in HDFS.
       If "false", permission checking is turned off,
       but all other behavior is unchanged.
       Switching from one parameter value to the other does not change the mode,
       owner or group of files or directories.
    </description>
 </property>
