      Description

      The description of SPARK-23916 refers to the implementation of array_join function in Presto. This implementation accepts arbitrary arrays of primitive types as an input.:

      presto> SELECT array_join(ARRAY [1, 2, 3], ', ');
      _col0
      ---------
      1, 2, 3
      (1 row)

      The goal of this Jira ticket is to change the current implementation of array_join function to support other types of arrays.
