Yin Huai commented on SPARK-15786:
----------------------------------
Is there any chance that we can let users know what is wrong exactly? This
error message is much better than the previous error. However, it looks like it
still does not point out what part of the user code is not allowed.
> 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
> Assignee: Sean Zhong
> Fix For: 2.0.0
>
>
> {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:
