Hi [~dibyad]: I have tried above steps with presto 0.217 + carbondata, I found steps is incorrect.

a) In create statement you have used same columns in inverted index as well as no inverted index, so create table failed. For this I removed no inverted index columns

b) I didn't see you mention, load data, so I loaded one row data  from spark and queried from presto

query success for me, didn't face any issue.

 

presto:db1> select * from inventory;
 inv_date_sk | inv_item_sk | inv_warehouse_sk | inv_quantity_on_hand 
-------------+-------------+------------------+----------------------
 1 | 2 | 3 | 30 
(1 row)

Splits: 17 total, 17 done (100.00%)
