Wayne Zhang created SPARK-19473: ----------------------------------- Summary: Several DataFrame Method still fail with dot in column names Key: SPARK-19473 URL: https://issues.apache.org/jira/browse/SPARK-19473 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 2.1.0 Reporter: Wayne Zhang
Here is an example: {code} val df = Seq((1.0, 2.0), (2.0, 3.0)).toDF("y.a", "x.b") df.select("y.a") org.apache.spark.sql.AnalysisException: cannot resolve '`y.a`' given input columns: [y.a, x.b];; df.withColumn("d", col("y.a") + col("x.b")) org.apache.spark.sql.AnalysisException: cannot resolve '`y.a`' given input columns: [y.a, x.b];; {code} We can use backquote to avoid the errors, but this behavior is affecting some downstream work such as RFormula and SparkR. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
