> Key: HBASE-4509
> URL: https://issues.apache.org/jira/browse/HBASE-4509
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.92.0, 0.94.0, 0.90.5
> Reporter: Jonathan Hsieh
> Assignee: Jonathan Hsieh
> Attachments: 0001-HBASE-4509-hbck-Improve-region-map-output.patch
>
>
> 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.
