             Summary: Implement evaluation of row-filter and masking expression for GDS
                 Key: RANGER-4827
                 URL: https://issues.apache.org/jira/browse/RANGER-4827
             Project: Ranger
          Issue Type: Improvement
          Components: plugins
            Reporter: Subhrat Chaudhary


Currently in GDS implementation, we have provision to ad row-filter and masking expression in the RangerGds.RangerSharedResource. But these are not evaluated during dataset policy evaluation. To extend the support of GDS in ranger, we can add evaluation of row-filter and masking expressions.

There can be one complexity while evaluation of row-filter and masking expressions for GDS:

For example: a dataset is linked with multiple SharedResource, with overlapping resources and the SharedResource has row-filter or masking expression added. In such case which expression should we consider for evaluation?

We need to address check and above issue.
