Key: PIG-1844
URL: https://issues.apache.org/jira/browse/PIG-1844
Project: Pig
Issue Type: Bug
Reporter: Mitesh Singh Jat
In Pig Grunt Shell, Hadoop fs commands, 'fs -mkdir' and 'fs -touchz' do not
support globbing (wild-cards) in their arguments.
This is inconsistent with the hadoop CLI interface, as well as internally
inconsistent as some other pig fs commands support glob string patterns.
The fs creation commands which create either directory {color:blue} fs -mkdir
{color} or file {color:blue} fs -touchz {color} are not handling globbing.
Whereas other commands like {color:blue} fs -ls {color} and {color:blue} fs
-rmr {color} are supporting globbing.

Hadoop CLI supports globbing for arguments of {color:blue} fs -mkdir {color}
and {color:blue} fs -touchz {color}.
{code:shell}
$ hadoop fs -mkdir temp_hadoop/dir{1,2,3}/data
$ hadoop fs -lsr temp_hadoop
