Dave Marion commented on ACCUMULO-1399:
---------------------------------------
[~sonixbp] I'm not sure that would work, you would have to have some way to
perform variable substitution in the scripts.
[~elserj] Thats an interesting idea that I had not thought of. You could create
an exec command that uses Jexl (or something like it) to run a script. The Jexl
engine could have a handle to the Shell object to invoke commands.
I was thinking of creating a class that contains shell commands. The jar that
contains the class would also need to conform to the spec for
java.util.ServiceLoader. Then in the shell, you could type:
{quote}
shell> myApp.createtable .... //creates a set of tables and configures
iterators on them, maybe sets the context classpath via a param
shell> myApp.backuptable .... //dumps the system config (ACCUMULO-1398) and
exports all tables in the set
shell> myApp.createuser .... //creates an entry for a user and their auths in
a table
{quote}
Some of these things might need namespaces (ACCUMULO-802). I have been
thinking about how multiple applications use the same Accumulo instance and
what might make multi-tenancy easier. That was the motivation behind
ACCUMULO-708.

> Proposing modification to the Shell to allow applications to create their own
> set of commands. This might be accomplished using java.util.ServiceLoader or
> something like it. Specifically, I'm thinking of a case where I have a create
> table command that is different than the one provided by the Shell. In my
> case, my create table command may create one or more tables and setup
> iterators on them.
