Zhihong Yu commented on HBASE-5122:
-----------------------------------

An alternative is to associate custom jar files (containing, e.g., 
ColumnInterpreter implementations) with tables.
Such association is expressed by a known table attribute.
There is redundancy in this approach, but we don't need to create new container.
                
> Provide flexible method for loading ColumnInterpreters

> From Royston:
> {noformat}
> I re-created my HBase table to contain Bytes.toBytes(Long) values and that 
> fixed it.
> {noformat}
> It was not the intention when AggregateProtocol was designed that users have 
> to change their schema to match LongColumnInterpreter.
> This JIRA aims to provide a flexible way for users to load their custom 
> ColumnInterpreters into region servers.
