Xiaoyu Yao commented on HADOOP-12358:
-------------------------------------
Thanks [~aw] for the suggestions to improve the usability and compatibility of
this feature.
bq. This limitation is tied to a flag on the rm command. Then we can write some
shell code to utilize .hadooprc to build subcommand aliasing. (.e.g., alias
"hadoop fs -rm"="hadoop fs -rm -safely" or whatever.) Just be aware that this
will only work in trunk.
I like this idea as it offers something close to GNU "rm -i", which is usually
aliased as "rm" in .bashrc for data safety.
> FSShell should prompt before deleting directories bigger than a configured

> We have seen many cases with customers deleting data inadvertently with
> -skipTrash. The FSShell should prompt user if the size of the data or the
> number of files being deleted is bigger than a threshold even though
> -skipTrash is being used.
