[GitHub] carbondata pull request #2786: [CARBONDATA-2967] Fixed NPE for preaggregate ...

[CARBONDATA-2967] Fixed NPE for preaggregate queries
**Problem:**
Preaggregate select queries require table path of parent table to access dictionary files. Therefore in executor CarbonMetadata class was used to get parent table object. As CarbonMetadata class is only meant to be used in driver and is not filled with carbontable objects for select queries therefore the query was throwing NPE.
**Solution:**
Pass parent table path from driver to executor by adding a new variable in RelationIdentifier. This will not be written to thrift, instead will be used to carry tablePath property from driver to executor.
Be sure to do all of the following checklist to help us incorporate

why for loop is duplicated, I think one time is once.

Is the `RelationIdentifier` is different objects in all dimensions? Isn't it a single object used in all dimensions.?
