Ted Yu created SPARK-11371: ------------------------------ Summary: Make "mean" an alias for "avg" operator Key: SPARK-11371 URL: https://issues.apache.org/jira/browse/SPARK-11371 Project: Spark Issue Type: Improvement Reporter: Ted Yu Priority: Minor
>From Reynold in the thread 'Exception when using some aggregate operators' >(http://search-hadoop.com/m/q3RTt0xFr22nXB4/): I don't think these are bugs. The SQL standard for average is "avg", not "mean". Similarly, a distinct count is supposed to be written as "count(distinct col)", not "countDistinct(col)". We can, however, make "mean" an alias for "avg" to improve compatibility between DataFrame and SQL. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
