      Description

      Following this[1] on the mailing list, it is not obvious how hbase will use a filter's read/write fields when there are multiple regions. Javadoc should be added explaining that for scans spanning multiple regions hbase will re-create the filter using the previous filter's writeFields instead of the original scan.
