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

             Summary: Support a default converter for data read shell commands
                 Key: HBASE-18067
                 URL: https://issues.apache.org/jira/browse/HBASE-18067
             Project: HBase
          Issue Type: Improvement
          Components: shell
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Minor
             Fix For: 2.0.0


The {{get}} and {{scan}} shell commands have the ability to specify some complicated syntax on how to encode the bytes read from HBase on a per-column basis. By default, bytes falling outside of a limited range of ASCII are just printed as hex.

It seems like the intent of these converts was to support conversion of certain numeric columns as a readable string (e.g. 1234).

However, if non-ascii encoded bytes are stored in the table (e.g. UTF-8 encoded bytes), we may want to treat all data we read as UTF-8 instead (e.g. if row+column+value are in Chinese). It would be onerous to require users to enumerate every column they're reading to parse as UTF-8 instead of the limited ascii range. We can provide an option to encode all values retrieved by the command.
