Subject Re: ColumnPaginationFilter called twice per line?

Ok. Confirmed. It's called twice:

2013-10-16 18:45:40,819 INFO
org.apache.hadoop.hbase.filter.ColumnPaginationFilter: A 9990
2013-10-16 18:45:40,819 INFO
org.apache.hadoop.hbase.filter.ColumnPaginationFilter: A 9990
2013-10-16 18:45:40,819 INFO
org.apache.hadoop.hbase.filter.ColumnPaginationFilter: A 9989
2013-10-16 18:45:40,819 INFO

Method filterKeyValue is called twice per cell version. I will try to
figure why.
