>                 Key: HBASE-9931
>                 URL: https://issues.apache.org/jira/browse/HBASE-9931
>             Project: HBase
>          Issue Type: Improvement
>          Components: mapreduce

> We've had CopyTable jobs fail because a small number of rows are wide enough to not fit
into memory.  If we could specify the batch size for CopyTable scans that shoud be able to
break those large rows up into multiple iterations to save the heap.
