Ajantha Bhat commented on CARBONDATA-3472:
------------------------------------------

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.
