> In production we have hundreds of tables w/ whack names like 'aliaserv', 'ashish_bulk',
'age_gender_topics', etc.  It be grand if you could look in master UI and see stuff like owner,
eng group responsible, miscellaneous description, etc.
> Now, HTD has support for this; each carries a dictionary.  Whats a PITA though is adding
attributes to the dictionary.  Here is what seems to work on trunk (though I do not trust
it is doing the right thing):
> {code}
> hbase> create 'SOME_TABLENAME', {NAME => 'd', VERSION => 1, COMPRESSION =>
'LZO'}
> hbase> # Here is how I added metadata
> hbase> disable 'SOME_TABLENAME'
> hbase> alter 'SOME_TABLENAME', METHOD => 'table_att', OWNER => 'SOMEON', CONFIG
=> {'ENVIRONMENT' => 'BLAH BLAH', 'SIZING' => 'The size should be between 0-10K most
of the time with new URLs coming in and getting removed as they are processed unless the pipeline
has fallen behind', 'MISCELLANEOUS' => 'Holds the list of URLs waiting to be processed
in the parked page detection analyzer in ingestion pipeline.'}
> ...
> describe...
> enable...
> {code}
> The above doesn't work in 0.94.  Complains about the CONFIG, the keyword we are using
for the HTD dictionary.
> It works in 0.96 though I'd have to poke around some more to ensure it is doing the right
thing.
> But this METHOD => 'table_att' stuff is really ugly.... can we fix it?
> And I can't add table attributes on table create seemingly.
> A little bit of thought and a bit of ruby could clean this all up.
