Subject Re: FuzzyRowFilter with ColumnRangeFilter
Date Mon, 29 Jul 2013 17:40:36 GMT
To run a single test, you should use the following command:

mvn test -PrunAllTests -DfailIfNoTests=false -Dtest=xxx

I ran TestColumnRangeFilter using tip of 0.94 code base and it passed.
Did you use tip of 0.94 ?

Cheers
