                 Key: HBASE-1210
                 URL: https://issues.apache.org/jira/browse/HBASE-1210
             Project: Hadoop HBase
          Issue Type: Improvement
            Reporter: Lars George
            Assignee: Lars George
            Priority: Trivial


Allow to chop the output of the values to be able to scan a table for specific 
rows and columns but without having the shell dump all the content of the cell 
value as it can potentially be very large. I suggest a hash called MAXLENGTH 
that can be added to the commands. For example:

get 'docs', 'ABCDE', { COLUMNS => 'contents:', MAXLENGTH => 150 }

and 

scan 'docs', { COLUMNS => 'contents:', MAXLENGTH => 150 }
