             Summary: Add some options to improve count performance
                 Key: HBASE-9086
                 URL: https://issues.apache.org/jira/browse/HBASE-9086
             Project: HBase
          Issue Type: Wish
          Components: shell
    Affects Versions: 0.94.2
            Reporter: Cheney Sun


The current count command in HBase shell is quite slow if the row size is very 
big (100+kB each). It would be helpful to provide some option to specify the 
column to count, which could give user a chance to reduce the data volume to 
scan. 
IMHO, only count the row key would be the ideal solution. Not sure how 
difficult to implement it.
