URL: https://issues.apache.org/jira/browse/ORC-1017
Project: ORC
Issue Type: Improvement
Reporter: Owen O'Malley

I want a tool that summarizes how the space inside an ORC file is used. In
particular, for each column, the indexes, the file footer, and the stripe
footers.
The output on the orc_split_elim_new.orc is:
{quote}Percent Bytes/Row Name
46.79 0.04 subtype
17.49 0.02 _file_footer
16.57 0.02 _index
7.01 0.01 decimal1
5.05 0.00 _stripe_footer
2.84 0.00 string1
2.59 0.00 ts
1.67 0.00 userid{quote}
