Summary: Adding confirm prompt when removing root directory on
local filesystem
Key: HDFS-16360
URL: https://issues.apache.org/jira/browse/HDFS-16360
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Yayu Wang
Would you like to add a confirm prompt when removing the root directory,
especially when using local filesystem? I forgot to set fs.defaultFS and
executed `rm -r /*` and it deleted everything on my local system. I lost
everything under my $HOME directory, and I think a sudo user may destroy the
host by doing so.
