Jesse Yates commented on HBASE-5548:
------------------------------------
bq. When I create a table, the output is kinda ugly? I suppose no way around
it.... its not end of world.
Doing a 360 on my comments above; looks like you can suppress it pretty easily,
if not entirely cleanly. I'd rather not hack the irb too much, but just do it
via changes to the methods on Table. Below is the output I have it using now.
{code}
1.9.2-p290 :002 > t = get_table 't'
0 row(s) in 0.0240 seconds
=>Hbase::Table - t
1.9.2-p290 :003 >
{code}
Essentially, we are just printing out the class and then the name of the table.
If we wanted to do more complicated things (for instance, print the CFs for
the table, or the whole descriptor) we can easily add it later to the
Table.to_s method.
Pretty clean and makes sense for people used to the ruby REPL as you see the
value of what you just got back (as a string).
bq. I'm thinking it might be nice to add in some help specific to a table
command more dynamically.
Punting on this - doubt it is going to be very rare that we will have to mod
the help for the command dynamically - you probably are changing the nature of
the command, so its really not worth it at the moment.

> Currently, all the commands that operate on a table in the shell first have
> to take the table as name as input.
> There are two main considerations:
> * It is annoying to have to write the table name every time, when you should
> just be able to get a reference to a table
> * the current implementation is very wasteful - it creates a new HTable for
> each call (but reuses the connection since it uses the same configuration)
> We should be able to get a handle to a single HTable and then operate on that.
