Dharmik Thakkar commented on HIVEMALL-280:
------------------------------------------
[~myui] Thanks!
I need one clarification on the input table 'transaction'. Does the
'transaction' table look like below?
!https://miro.medium.com/max/678/1*K2f-Rja-1xrqe9IdUy5Dgw.png!
And in the query the arguments to lift/confidence/support would be all the
three columns? Is this understanding correct? Please suggest. Thanks!
