Sean Owen commented on SPARK-17908: ----------------------------------- Can you provide the error and a self-contained reproduction? I can't reproduce that on similar code but there's probably something different in what you're actually doing. > Column names Corrupted in pysaprk dataframe groupBy > --------------------------------------------------- > > Key: SPARK-17908 > URL: https://issues.apache.org/jira/browse/SPARK-17908 > Project: Spark > Issue Type: Bug > Components: PySpark > Affects Versions: 1.6.0, 1.6.1, 1.6.2, 2.0.0, 2.0.1 > Reporter: Harish > Priority: Minor > > I have DF say df > df1= df.groupBy('key1', 'key2', > 'key3').agg(func.count(func.col('val')).alias('total')) > df3 =df.join(df1, ['key1', 'key2', 'key3'])\ > .withcolumn('newcol', func.col('val')/func.col('total')) > I am getting key2 is not present in df1, which is not truw becuase df1.show > () is having the data with the key2. > Then i added this code before join-- df1 = df1.columnRenamed('key2', 'key2') > renamed with same name. Then it works. > Stack trace will say column missing, but it is npt. -- 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
