Using Deequ 1.1 with Spark 3

#apachespark #awsdeequ #deequ #dataquality

If you try to upgrade AWS Deequ to latest version (1.1.0) atm and use with Spark 3.0.1 you will get following error:

[error] (update) Conflicting cross-version suffixes in: org.apache.spark:spark-launcher, org.apache.spark:spark-sketch, org.apache.spark:spark-kvstore, org.json4s:json4s-ast, org.apache.spark:spark-catalyst, org.apache.spark:spark-network-shuffle, com.twitter:chill, org.apache.spark:spark-sql, org.scala-lang.modules:scala-xml, org.json4s:json4s-jackson, com.fasterxml.jackson.module:jackson-module-scala, org.json4s:json4s-core, org.apache.spark:spark-unsafe, org.json4s:json4s-scalap, org.scala-lang.modules:scala-parser-combinators, org.apache.spark:spark-tags, org.apache.spark:spark-core, org.apache.spark:spark-network-common

This is due to the fact that Deque has transitive dependencies to Scala 2.11 for some unknown reason (a bug?). You can fix that by using the following build.sbt:

name := "dq"

scalaVersion := "2.12.12"

val sparkVersion = "3.0.1"

libraryDependencies += "org.apache.spark" %% "spark-sql" % sparkVersion % "provided"


// https://mvnrepository.com/artifact/com.amazon.deequ/deequ
// issue with Deequ transitive libs cross-compiled to Scala 2.11
libraryDependencies += ("com.amazon.deequ" % "deequ" % "1.1.0_spark-3.0-scala-2.12")
