Github user ouyangxiaochen commented on the issue: https://github.com/apache/spark/pull/17628 I serached the instance of var foo = "string" with the RegEx ` \s*var [a-z|A-Z]* = "*"` in whole project and there are 31 of them. The usage of them are almost reasonable except the file `SparkSQLCLIDriver`. @srowen cc
