             Summary: enhance HLog pretty printer to print additional useful stats
                 Key: HBASE-5907

          Issue Type: Improvement
            Reporter: Kannan Muthukkaruppan
            Priority: Minor

It would be useful for analysis purposes to enhance the HLog pretty printer to optionally
print a bunch of additional stats such as:

1) # of txns
2) # of KVs updated
3) avg size of txns
4) avg size of KVs
5) avg # of KVs written per txn
5) unique CF signatures involved in put/delete operatons; and breakdown of some of the above
metrics by these signatures, etc.
