> When running an investigative job, I used a date parameter that selected multiple directories
for the input (e.g. "my_data/2012/06/{18,19,20}"). It used this same date parameter when creating
the output directory.
> But `hadoop fs` was unable to ls, getmerge, or rmr it until I used the regex operator
"?" and mv to change the name (that is, `-mv output/2012/06/?18,19,20? foobar").
> Shells and filesystems for other systems provide a means of escaping "special characters"
generically, but there seems to be no such means in HDFS/`hadoop fs`. Providing one would
be a great way to make accessing HDFS more robust.
