----------------------------------------

             Summary: Add non empty check for UDF location in getLastModifiedTime method
                 Key: IMPALA-12121
                 URL: https://issues.apache.org/jira/browse/IMPALA-12121
             Project: IMPALA
          Issue Type: Improvement
          Components: fe
            Reporter: Soumyakanti Das


{{getLastModifiedTime()}} of {{Function.java}} assumes that if the UDF is not a BUILTIN and if the location is not null, it is a non-empty string. However, we may have UDFs with an empty location if they are in the install location and loaded at init time.

We should also add a non empty check for the location in the if condition.
