------------------------------------

             Summary: Support CarbonCli tool for data summary
                 Key: CARBONDATA-2916
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-2916
             Project: CarbonData
          Issue Type: New Feature
            Reporter: Jacky Li


When I am tuning carbon performance, very often that I want to check the metadata in carbon files without launching spark shell or sql. In order to do that, I am writing a tool to print metadata information of a given data folder.
Currently, I am planning to do like this:

usage: CarbonCli
 -a,--all                    print all information
 -b,--tblProperties          print table properties
 -c,--column <column name>   column to print statistics
 -cmd <command name>         command to execute, supported commands are:
                             summary
 -d,--detailSize             print each blocklet size
 -h,--help                   print this message
 -m,--showSegment            print segment information
 -p,--path <path>            the path which contains carbondata files,
                             nested folder is supported
 -s,--schema                 print the schema

In first phase, I think “summary” command is high priority, and developers can add more command in the future.
