-------------------------------------
Summary: 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: 2.2.0, 2.1.1
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:
{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}
