Jesse Yates commented on HBASE-4879:
------------------------------------

As a follow-on ticket to 4605, this means adding the support for altering a=
 table more easily. Specifically, this means doing something like:

{code}
alter("table").addCoprocessor(=E2=80=A6)
alter("table").addColumnFamily(=E2=80=A6)
=E2=80=A6
{code}

and then for constraints, something like:

{code}
alter("table").addConstraint(=E2=80=A6)
alter("table").enableConstraints
=E2=80=A6
{code}

with those methods being added dynamically by a 'constraint module' in the =
jruby code. This would also serve as an example for how further shell exten=
sion can be done in a modular manner.

This ticket may also become a more major revamp for the how the shell works=
, e.g. dropping into a table context, etc as described in the discussion.=
