Therefor I have not been able to do a run of my test, so far. I can however
attach it here, if someone who does not run into this problem is willing to
give it a try.
> Add BigDecimalColumnInterpreter for doing aggregations using AggregationClient
> ------------------------------------------------------------------------------
>
> Key: HBASE-6669
> URL: https://issues.apache.org/jira/browse/HBASE-6669
> Project: HBase
> Issue Type: New Feature
> Components: client, coprocessors
> Reporter: Anil Gupta
> Priority: Minor
> Labels: client, coprocessors
> Attachments: BigDecimalColumnInterpreter.java,
> BigDecimalColumnInterpreter.patch, BigDecimalColumnInterpreter.patch
>
>
> I recently created a Class for doing aggregations(sum,min,max,std) on values
> stored as BigDecimal in HBase. I would like to commit the
> BigDecimalColumnInterpreter into HBase. In my opinion this class can be used
> by a wide variety of users. Please let me know if its not appropriate to add
> this class in HBase.
> Thanks,
