[jira] [Created] (MADLIB-1442) Do not try to drop output tables

Orhan Kislal created MADLIB-1442:
------------------------------------

             Summary: Do not try to drop output tables
                 Key: MADLIB-1442
                 URL: https://issues.apache.org/jira/browse/MADLIB-1442
             Project: Apache MADlib
          Issue Type: Improvement
          Components: All Modules
            Reporter: Orhan Kislal
             Fix For: v1.18.0


It seems MADlib drops the output table before creating a new one in some modules. We should not do this, instead, the user should be warned of the issue.

In some cases, we first check if the output table exists and then try to drop the non-existent table anyway. We should remove these queries as well.

The list of modules that might have this issue:

Summary, assoc_rules, glm, pca_project, logistic regression
