-----------------------------------
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.
