Michael Armbrust updated SPARK-15786:
-------------------------------------
    Target Version/s: 2.0.0

> joinWith bytecode generation calling ByteBuffer.wrap with InternalRow
> ---------------------------------------------------------------------
>
>                 Key: SPARK-15786
>                 URL: https://issues.apache.org/jira/browse/SPARK-15786
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.6.1, 2.0.0
>            Reporter: Richard Marscher
>
> {code}java.lang.RuntimeException: Error while decoding: 
> java.util.concurrent.ExecutionException: java.lang.Exception: failed to 
> compile: org.codehaus.commons.compiler.CompileException: File 
> 'generated.java', Line 36, Column 107: No applicable constructor/method found 
> for actual parameters "org.apache.spark.sql.catalyst.InternalRow"; candidates 
> are: "public static java.nio.ByteBuffer java.nio.ByteBuffer.wrap(byte[])", 
> "public static java.nio.ByteBuffer java.nio.ByteBuffer.wrap(byte[], int, 
> int)"{code}
> I have been trying to use joinWith along with Option data types to get an 
> approximation of the RDD semantics for outer joins with Dataset to have a 
> nicer API for Scala. However, using the Dataset.as[] syntax leads to bytecode 
> generation trying to pass an InternalRow object into the ByteBuffer.wrap 
> function which expects byte[] with or without a couple int qualifiers.
> I have a notebook reproducing this against 2.0 preview in Databricks 
> Community Edition: 
> https://databricks-prod-cloudfront.cloud.databricks.com/public/4027ec902e239c93eaaa8714f173bcfc/160347920874755/1039589581260901/673639177603143/latest.html
