Matteo Bertozzi commented on HBASE-3929:
----------------------------------------
>From 0.92 the HFile.main() contains just a call to HFilePrettyPrinter.run()
So there's no more the "Tool" code inside the HFile.java
Probably was not the refactor that todd has in mind, but it solve the first
todd's thought:
'we should refactor all of the HFile "Tool" stuff out of HFile into a new
class.'
> Add option to HFile tool to produce basic stats

> In looking at HBASE-3421 I wrote a small tool to scan an HFile and produce
> some basic statistics about it:
> - min/mean/max key size, value size (uncompressed)
> - min/mean/max number of columns per row (uncompressed)
> - min/mean/max number of bytes per row (uncompressed)
> - the key of the largest row
