chendihao commented on HBASE-9800:
----------------------------------
Yes, I know AggregationClient.rowCount(). We write a main function to call it
from time to time. Because it's not quite real-time, we have a plan to count
the rows daily at midnight. It might be helpful for us to know the rough
statistics about tables while not affecting the online services.
> Impl CoprocessorRowcounter to run in command-line

> Key: HBASE-9800
> URL: https://issues.apache.org/jira/browse/HBASE-9800
> Project: HBase
> Issue Type: New Feature
> Components: Coprocessors
> Affects Versions: 0.94.3
> Reporter: chendihao
> Priority: Minor
>
> We want to count the rows of table daily but the default rowcounter using
> mapreduce is inefficient. Impl rowcounter using coprocessor makes it better.
> Furthermore, It must provide the mechanism to choose the way to output result.
