Summary: Support protected path configuration
Key: HDFS-13037
URL: https://issues.apache.org/jira/browse/HDFS-13037
Project: Hadoop HDFS
Issue Type: New Feature
Components: namenode
Reporter: chuanjie.duan
After Hadoop2.7 root path("/") cannot be deleted for any situration. But like
'/tmp','/user','/user/hive/warehouse' and so on, shouldn't be deleted mostly.
So can we add a configuration, then user can custom their own protected path.
Just for any accident.
1. add configuration to hdfs-site.xml
2. add a command in dfsadmin for refreshingÂ
