             Summary: Extend rcfilecat to support uncompressed size and no. of row
                 Key: HIVE-4056
                 URL: https://issues.apache.org/jira/browse/HIVE-4056
             Project: Hive
          Issue Type: Bug
          Components: Statistics
            Reporter: Gang Tim Liu
            Assignee: Gang Tim Liu


rcfilecat supports data and metadata:
https://cwiki.apache.org/Hive/rcfilecat.html

In metadata, it supports column statistics.

It will be natural to extend metadata support to 
1. no. of rows 
2. uncompressed size for the file
3. compressed size for the file
