stack commented on HBASE-4509:
------------------------------

Fails when I try apply to 0.92 and trunk.  Want to fix Jon (I'd mess it up I'd say hacking
it into 0.92...)

> HBASE-4375 added a region coverage visualization to hbck in details mode.  When users
have binary row keys the output is difficult to parse (awk/sed) or pull into programs (numeric,
excel) capable of handling tsv formatted data.
> This patch 
> * improves output by using Bytes.toStringBinary (which escapes binary) instead of Bytes.toString
when printing keys, 
> * suggests some repair actions, and 
> * collects "problem group" that groups regions that are overlapping.
