Description

Hadoop fs commands support globbing during deleting files/dirs. Pig is not consistent with this behavior and seems like we could change rm/rmf commands to do the same.

For eg:

localhost:pig pkommireddi$ ls -ld out*
drwxr-xr-x  12 pkommireddi  SF\domain users  408 Feb 13 01:09 out
drwxr-xr-x   2 pkommireddi  SF\domain users   68 Feb 13 01:16 out1
drwxr-xr-x   2 pkommireddi  SF\domain users   68 Feb 13 01:16 out2

localhost:pig pkommireddi$ bin/pig -x local
grunt> rmf out*
grunt> quit

localhost:pig pkommireddi$ ls -ld out*
drwxr-xr-x  12 pkommireddi  SF\domain users  408 Feb 13 01:09 out
drwxr-xr-x   2 pkommireddi  SF\domain users   68 Feb 13 01:16 out1
drwxr-xr-x   2 pkommireddi  SF\domain users   68 Feb 13 01:16 out2

Ideally, the user would expect "rmf out*" to delete all of the above dirs.
