Riley Patterson updated HBASE-3968:
-----------------------------------
Release Note: Implementation of a Pretty Printer for HLogs. Can be accessed
with the Java API or with a command line interface, which replaces HLog --dump
functionality. Can output to a human-readable pretty format, or to a JSON list
for easy parsing in diagnostic scripts. Can also filter by region, row, and/or
sequence id. See command line usage (HLog --dump -h) and the javadocs for more
detail on these features.
Status: Patch Available (was: Open)

> 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)
