Subject [jira] Created: (HADOOP-1789) [hbaseshell] output formatting

[hbaseshell] output formatting
------------------------------

                 Key: HADOOP-1789
                 URL: https://issues.apache.org/jira/browse/HADOOP-1789
             Project: Hadoop
          Issue Type: New Feature
            Reporter: stack
            Priority: Minor


hbaseshell currently outputs results using an ascii table.

This issue is about the hbaseshell offering a number of output formats beyond plain ascii
table.  It would be grand if output formatting was pluggable so folks could add new ones as
they saw fit.

Currently, there is a painful need for unadorned output so folks can do a 'select page:content
from webrepository where row="http://apache.com/index.html"; and they get back the page content
only.  Other output formats might be: csv, xml, or (x)html

Other related things to consider, but probably not as part of this issue, is that if we output
xml, then we should probably have a sympathetic input parser for xml files (similar for csv).
 Let this issue just be about formatting (another issue can be done to add pluggable input
parsers).  Where the output lands should also be done in another issue: i.e. dependent on
the command, output probably default to stdout but folks should be able to designate an output
file (and target filesystem) as in hdfs://master.hdfsnode.com:8990/output/dump.txt or file:///tmp/dump.txt
or s3://...., etc.

This issue is an outgrowth of HADOOP-1720
