> Fix key/value schema field names in HashMapGenerators.
> ------------------------------------------------------
>
> Key: SPARK-22273
> URL: https://issues.apache.org/jira/browse/SPARK-22273
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.1.1, 2.2.0
> Reporter: Takuya Ueshin
> Priority: Minor
>
> When fixing schema field names using escape characters with {{addReferenceMinorObj()}} at SPARK-18952, double-quotes around the names were remained and the names become something like {{"((java.lang.String) references\[1\])"}}.
> {code}
> /* 055 */ private int maxSteps = 2;
> /* 056 */ private int numRows = 0;
> /* 057 */ private org.apache.spark.sql.types.StructType keySchema = new org.apache.spark.sql.types.StructType().add("((java.lang.String) references[1])", org.apache.spark.sql.types.DataTypes.StringType);
> /* 058 */ private org.apache.spark.sql.types.StructType valueSchema = new org.apache.spark.sql.types.StructType().add("((java.lang.String) references[2])", org.apache.spark.sql.types.DataTypes.LongType);
> /* 059 */ private Object emptyVBase;
> {code}
> We should remove the double-quotes to refer the values in {{references}} properly:
