[jira] [Created] (SPARK-18892) Alias percentile_approx approx_percentile

Reynold Xin created SPARK-18892:
-----------------------------------

             Summary: Alias percentile_approx approx_percentile
                 Key: SPARK-18892
                 URL: https://issues.apache.org/jira/browse/SPARK-18892
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
            Reporter: Reynold Xin
            Assignee: Reynold Xin


percentile_approx is the name used in Hive, and approx_percentile is the name used in Presto. approx_percentile is actually more consistent with our approx_count_distinct. Given the cost to alias SQL functions is low (one-liner), it'd be better to just alias them so it is easier to use.
