[~qwertymaniac] do the changes in HBASE-11658 satisfy your needs here?

URL: https://issues.apache.org/jira/browse/HBASE-5842
Project: HBase
Issue Type: Improvement
Components: shell
Affects Versions: 0.94.0
Reporter: Harsh J
Priority: Minor
Many times we've required scans of .META. to analyze issues with the cluster
we work on, and to have the result in a file we can pass around we usually
end up doing something like:
{{echo scan '.META.'| hbase shell meta-scan.txt}}
This can rather be simplified as something like the following instead, with
support for a commands reading argument:
{{hbase shell -c scan '.META.'}}
[Note though: File reading is possible already, i.e. {{hbase shell file.hs}},
but then thats two steps and we usually don't keep a file around for just a
meta table scan.]

@Jon http://svn.apache.org/viewvc/hbase/tags/0.18.1/bin/ has a Formatter.rb
class. You have to go back further to find our being able to format output as
html:
http://svn.apache.org/viewvc/hbase/tags/0.1.3/src/java/org/apache/hadoop/hbase/hql/TableFormatterFactory.java?view=markup
@Harsh -c sounds good easier than echo blah blah.

Harsh J commented on HBASE-5842:
It exists in 0.90+ AFAIK. However this JIRA is about adding in a -c option not
just for META scan but also to run any other series of ;-separated commands
without having to echo and pipe it into the shell.

We used to have it so you could pass a formatter class that the shell would
use. Default is console formatting. We used to have an html output one which
was useful when you could type in shell commands on ui and get results as an
html page. Another formatter would emit results per line so greppable.

Harsh, I would add that the output from the shell of that particular example
is too clever with formatting and ends up being cumbersome to use with standard
unix parsing tools.
For that particular command, I've hacked the HFile tool do dump contents in an
grep'able format.
Are you looking for that command in particular or are there more cases?
Maybe we should add a hbase-admin command that has shortcuts to utility methods
like HLog, HFile, and something like DumpMeta?
