Ted Yu commented on SPARK-11371: -------------------------------- [~sowen]: Do you think it is worth adding the alias ? Thanks > Make "mean" an alias for "avg" operator > --------------------------------------- > > Key: SPARK-11371 > URL: https://issues.apache.org/jira/browse/SPARK-11371 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Ted Yu > Priority: Minor > Attachments: spark-11371-v1.patch > > > 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
