RE: Delete a folder name containing *
Escape character is \, but please enclose with single quote
For example /foo/{123} should be '/foo/\{123\}'

Re: Delete a folder name containing *
With renaming - you would use the mv command hadoop fs -mv /data/folder* /data/new_folder. Won't it move all the sub_dirs along with that ?

Re: Delete a folder name containing *
Try hadoop fs -mv /data/folder*/* new folder Now you have only /data/folder*. and all data under /data/folder* will be moved to new folder ,then delete /data/folder*.Not sure if it works. just make a try.

Re: Delete a folder name containing *
No, I have tried all usual things like single quotes, double quotes, escape character.. but it is not working. I wonder what is escape char with Hadoop FS utility.

interesting ... although escape character is still the forward slash and its proven to work with other special characters.
