Barry Becker created SPARK-18502:
------------------------------------
Summary: Spark does not handle columns that contain backquote (`)
Key: SPARK-18502
URL: https://issues.apache.org/jira/browse/SPARK-18502
Project: Spark
Issue Type: Bug
Components: Spark Core
Reporter: Barry Becker
Priority: Minor
I know that if a column contains dots or hyphens we can put
backquotes/backticks around it, but what if the column contains a backtick (`)?
Can the back tick be escaped by some means?
Here is an example of the sort of error I see
{code}
org.apache.spark.sql.AnalysisException: syntax error in attribute name:
