Deepa Vasanthkumar commented on HBASE-10463:
--------------------------------------------
Thanks [~ndimiduk]
The approach was just to create a Comparator class which extends
WritableByteArrayComparable, and provided compareTo which uses BigDecimal
comparsion.
I am interested in contributing this. I will go through the article
http://hbase.apache.org/book/submitting.patches.html and will update shortly.
> Filter on columns containing numerics yield wrong results

> Key: HBASE-10463
> URL: https://issues.apache.org/jira/browse/HBASE-10463
> Project: HBase
> Issue Type: Improvement
> Components: Filters
> Affects Versions: 0.94.8
> Reporter: Deepa Vasanthkumar
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> Used SingleColumnValueFilter with CompareFilter.CompareOp.GREATER_OR_EQUAL
> for filtering the scan result.
> However the columns which have numeric value, scan result is not correct,
> because of lexicographic comparison.
> Does HBase support numeric value filters (for equal, greater or equal..) for
> columns ? If not, can we add it?
