Nicolas Spiegelberg commented on HBASE-3968:
--------------------------------------------
@Todd: our internal branches do not have Avro support, so that's a little
overkill for us but might be good for a subsequent task. The thought was that
JSON encoding will allow us to easily feed the data into a Python/Ruby script
to do any in-depth analysis that shell scripting falls short on.

> We currently have a rudimentary way to print HLog data, but it is limited and
> currently prints key-only information. We need extend this functionality,
> similar to how we developed HFile's pretty printer. Ideas for functionality:
> - filter by sequence_id
> - filter by row / region
> - option to print values in addition to key info
> - option to print output in JSON format (so scripts can easily parse for
> analysis)
