Subject [jira] [Commented] (ACCUMULO-4544) pluggable parser for insert shell command
Date Thu, 29 Dec 2016 07:46:58 GMT

Christopher Tubbs commented on ACCUMULO-4544:
---------------------------------------------

I'm not sure it's a good idea to try to turn the shell into a full-featured client for arbitrary
user data models. The formatter was added primarily as a very low-effort way of assisting
debugging using the shell.

If we're really going to go hard-core down the path of making the shell do application-specific
2-way data model transformations, I really don't think the shell is well-suited for that.
It'd be far better to do something like ACCUMULO-1045 and use/build tools external to Accumulo
for these kinds of things. Otherwise, I think we risk more scope-creep and bit rot, with a
lot of new and complex code for a shell that already has numerous unfixed issues with input
and parsing.

> Just as you can attach custom formatters for scan output in the shell, it would be great
to be able to provide the inverse transformation for use when inserting. right now, if you
are using a formatter on a table, you typically cannot copy lines to reinsert with modifications,
without also manually reversing whatever your formatter is doing.
