Subject [jira] [Created] (HDFS-3557) provide means of escaping special characters to `hadoop fs` command
Date Fri, 22 Jun 2012 18:40:43 GMT
Jeff Hodges created HDFS-3557:

             Summary: provide means of escaping special characters to `hadoop fs` command
                 Key: HDFS-3557
                 URL: https://issues.apache.org/jira/browse/HDFS-3557
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Jeff Hodges
            Priority: Minor

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.
