> Currently we create bitmap index for all druid dimensions. 
> For some columns (e.g Free form text, high cardinality columns that are rarely filtered
upon), It may be beneficial to skip creating druid bitmap index and save disk space.  
> In druid https://github.com/apache/incubator-druid/pull/5402 added support for creating
string dimension columns without bitmap indexes. 
> This task is to add similar option when indexing data from hive.
