Jacky Li updated CARBONDATA-312:
--------------------------------
Description:
Take CarbonDatasourceHadoopRelation as the target datasource definition, after
that, CarbonContext can use standard Datasource strategy
In this Issue, following change is required:
1. Move the dictionary stratey out of CarbonTableScan, make a separate strategy
for it.
2. CarbonDatasourceHadoopRelation should use CarbonScanRDD in buildScan
function.
3. Change CarbonSource to use CarbonDatasourceHadoopRelation only, remove
extension of BaseRelation, extend from HadoopFsRelation only.
