Fix Version/s: 2.2.0
> codehaus fails to generate code because of unescaped strings

> I guess somewhere along the way Spark uses codehaus to generate optimized
> code, but if it fails to do so, it falls back to an alternative way. Here's a
> log string that I see when executing one command on dataframes:
> 17/05/02 12:00:14 ERROR CodeGenerator: failed to compile:
> org.codehaus.commons.compiler.CompileException: File 'generated.java', Line
> 93, Column 13: ')' expected instead of 'type'
> ...
> /* 088 */ private double loadFactor = 0.5;
> /* 089 */ private int numBuckets = (int) (capacity / loadFactor);
> /* 090 */ private int maxSteps = 2;
> /* 091 */ private int numRows = 0;
> /* 092 */ private org.apache.spark.sql.types.StructType keySchema = new
> org.apache.spark.sql.types.StructType().add("taxonomyPayload",
> org.apache.spark.sql.types.DataTypes.StringType)
> /* 093 */ .add("{"type":"nontemporal"}",
> org.apache.spark.sql.types.DataTypes.StringType)
> /* 094 */ .add("spatialPayload",
> org.apache.spark.sql.types.DataTypes.StringType);
> /* 095 */ private org.apache.spark.sql.types.StructType valueSchema = new
> org.apache.spark.sql.types.StructType().add("sum",
> org.apache.spark.sql.types.DataTypes.DoubleType);
> /* 096 */ private Object emptyVBase;
> /* 097 */ private long emptyVOff;
> /* 098 */ private int emptyVLen;
> /* 099 */ private boolean isBatchFull = false;
> /* 100 */
> It looks like on line 93 it failed to escape that string (that happened to be
> in my code). I'm not sure how critical this is, but seems like there's
> escaping missing somewhere.
> Stack trace that happens afterwards: https://pastebin.com/NmgTfwN0
