haosdent commented on HBASE-10848:
----------------------------------
For this issue, I think just test NullComparator#compareTo would be enough. It
is not necessary to test it through start a miniCluster. Just my opinion.
> Filter SingleColumnValueFilter combined with NullComparator does not work

> I want to filter out from the scan the rows that does not have a specific

> But every time I use this in a scan, I get the following exception:
