> Improvements
> - Make the sniff of region and regionserver parallel to support large cluster with 10000+
region and 500+ regionservers using thread pool.
> - Set cacheblock to false in get and scan to avoid influence to block cache.
> - Add FirstKeyOnlyFilter to get and scan to avoid read and translate too many data from
HBase. There may be many column under a column family in a flat-wide table.
>  - Select the region randomly when sniffing a regionserver.
>  - Make the sink class of canary configurable
> [~stack]
> Suggestions are welcomed. Thanks~
> Another question is that why to check each column family with separate requests when
sniffing a region? Can we just check a  column family of a region?
