             Summary: Add option to summarize block sizes to rfile-print info
                 Key: ACCUMULO-1886
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1886
             Project: Accumulo
          Issue Type: Improvement
            Reporter: Keith Turner


rfile print info command can generate a historgram of rfile key/value sizes.  It does this
by scanning all of the data in the rfile.  The rfile index keeps track of  the compressed
and uncompressed size of each key/value block.  

Generating a histogram block sizes would be very quick and would give an approximation of
the key/value size histogram for larger key values.  It would be useful to add this as an
option to print-info.
