Apache Spark reassigned SPARK-12558: ------------------------------------ Assignee: Apache Spark > AnalysisException when multiple functions applied in GROUP BY clause > -------------------------------------------------------------------- > > Key: SPARK-12558 > URL: https://issues.apache.org/jira/browse/SPARK-12558 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 1.6.0 > Reporter: Maciej BryĆski > Assignee: Apache Spark > > Hi, > I have following issue when trying to use functions in group by clause. > Example: > {code} > sqlCtx = HiveContext(sc) > rdd = sc.parallelize([{'test_date': 1451400761}]) > df = sqlCtx.createDataFrame(rdd) > df.registerTempTable("df") > {code} > Now, where I'm using single function it's OK. > {code} > sqlCtx.sql("select cast(test_date as timestamp) from df group by > cast(test_date as timestamp)").collect() > [Row(test_date=datetime.datetime(2015, 12, 29, 15, 52, 41))] > {code} > Where I'm using more than one function I'm getting AnalysisException > {code} > sqlCtx.sql("select date(cast(test_date as timestamp)) from df group by > date(cast(test_date as timestamp))").collect() > Py4JJavaError: An error occurred while calling o38.sql. > : org.apache.spark.sql.AnalysisException: expression 'test_date' is neither > present in the group by, nor is it an aggregate function. Add to group by or > wrap in first() (or first_value) if you don't care which value you get.; > {code} -- 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
