>                 Key: PHOENIX-4266
>                 URL: https://issues.apache.org/jira/browse/PHOENIX-4266
>             Project: Phoenix
>          Issue Type: Bug
>            Reporter: Lars Hofhansl
>            Priority: Major
>
> Phoenix tries to set caching on all scans. On HBase versions before 0.98 that 
> made sense, now it is the wrong thing to do.
> HBase will by default do size based chunking. Setting scanner caching 
> prevents HBase doing this work.
> We should avoid scanner everywhere, and only use in cases where we know the 
> number of rows to be returned (and that number is small).
