Hello everyone, I'm trying to implement new encoder, which will be able to encode Kotlin data classes.
They can be generics, so I'm calculating their types in compiletime. My trouble is I have following code generated: /* 197 */ final InternalRow deserializetoobject_value_9 = false ? /* 198 */ null : new kotlin.Pair(deserializetoobject_argValue_1, deserializetoobject_mutableStateArray_1[0]); It's obvious that InternalRow can't be assigned with kotlin.Pair And therefore errors like this: 20/03/19 16:31:18 ERROR CodeGenerator: failed to compile: org.codehaus.commons.compiler.CompileException: File 'generated.java', Line 195, Column 74: Assignment conversion not possible from type "kotlin.Pair" to type "org.apache.spark.sql.catalyst.InternalRow" Here [1] I put gist with more code: mine and generated and also stacktace I'm building my encoder against current spark snapshot Thank you, Pasha 1. https://gist.github.com/asm0dey/14d5b8aa289403251a7110e5522cff38
