Richard Marscher created SPARK-15786: ----------------------------------------
Summary: Spark SQL - 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
