>
> The essential column family feature makes queries slower in 0.94.6 and below.
> We should add a configuration option to disable it. It's enabled in
> QueryCompiler by setting the LOAD_COLUMN_FAMILIES_ON_DEMAND_ATTR to true.
> Ideally, we should detect the lower HBase region server version. We could
> pass this back at initial cluster connection (MetaDataProtocol.getVersion()
> call).
> Another option would be to have the config option, set it to on by default,
> but let users know that if they're using 0.94.6 or below, then should set it
> to off.
