[jira] [Created] (HDFS-3557) provide means of escaping special
characters to `hadoop fs` command
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.
