Constraints are not overriding for new Table Checks

[anamikasingh-bigdata]

I am using Amazon Deequ for Multiple Tables check using loop. For first table Rules, output looks good, but for next tables its failing in bad way because Constraints for older table's rule also getting checks and those all are failing due to column not found. How to delete all the older constraints in loop while it is starting for next table. after reassigning value as var checks: Check = null also not working. Please help how to delete all the older table Constraints in Scala. If possible, kindly provide the code. Thanks.
