Sean Owen commented on SPARK-16874:
-----------------------------------

Sounds related to if not a duplicate of things like https://issues.apache.org/jira/browse/SPARK-12988 I think you have to back-tick columns like this now? It's not necessarily true that behavior is the same across major releases.

> I was porting some code I had from spark 1.6.2 to 2.0.0 and while reading a CSV file, I've stumbled into the following error :
> {code} org.apache.spark.sql.AnalysisException: Unable to resolve row.names given [row.names, sbp, tobacco, ldl, adiposity, famhist, typea, obesity, alcohol, age, chd];
> {code}
> There is is of course a work around using a predefined schema but it's not very practical if there is lots of columns
> I've provided in the following link code snippets that can generate the error for spark 2.0 and another that show how it works perfectly with 1.6.2 using the spark-csv package :
