Apache Spark commented on SPARK-7726: ------------------------------------- User 'pwendell' has created a pull request for this issue: https://github.com/apache/spark/pull/8095 > Maven Install Breaks When Upgrading Scala 2.11.2-->[2.11.3 or higher] > --------------------------------------------------------------------- > > Key: SPARK-7726 > URL: https://issues.apache.org/jira/browse/SPARK-7726 > Project: Spark > Issue Type: Bug > Components: Build > Reporter: Patrick Wendell > Assignee: Iulian Dragos > Priority: Blocker > Fix For: 1.4.0 > > > This one took a long time to track down. The Maven install phase is part of > our release process. It runs the "scala:doc" target to generate doc jars. > Between Scala 2.11.2 and Scala 2.11.3, the behavior of this plugin changed in > a way that breaks our build. In both cases, it returned an error (there has > been a long running error here that we've always ignored), however in 2.11.3 > that error became fatal and failed the entire build process. The upgrade > occurred in SPARK-7092. Here is a simple reproduction: > {code} > ./dev/change-version-to-2.11.sh > mvn clean install -pl network/common -pl network/shuffle -DskipTests > -Dscala-2.11 > {code} > This command exits success when Spark is at Scala 2.11.2 and fails with > 2.11.3 or higher. In either case an error is printed: > {code} > [INFO] > [INFO] --- scala-maven-plugin:3.2.0:doc-jar (attach-scaladocs) @ > spark-network-shuffle_2.11 --- > /Users/pwendell/Documents/spark/network/shuffle/src/main/java/org/apache/spark/network/shuffle/protocol/UploadBlock.java:56: > error: not found: type Type > protected Type type() { return Type.UPLOAD_BLOCK; } > ^ > /Users/pwendell/Documents/spark/network/shuffle/src/main/java/org/apache/spark/network/shuffle/protocol/StreamHandle.java:37: > error: not found: type Type > protected Type type() { return Type.STREAM_HANDLE; } > ^ > /Users/pwendell/Documents/spark/network/shuffle/src/main/java/org/apache/spark/network/shuffle/protocol/RegisterExecutor.java:44: > error: not found: type Type > protected Type type() { return Type.REGISTER_EXECUTOR; } > ^ > /Users/pwendell/Documents/spark/network/shuffle/src/main/java/org/apache/spark/network/shuffle/protocol/OpenBlocks.java:40: > error: not found: type Type > protected Type type() { return Type.OPEN_BLOCKS; } > ^ > model contains 22 documentable templates > four errors found > {code} > Ideally we'd just dig in and fix this error. Unfortunately it's a very > confusing error and I have no idea why it is appearing. I'd propose reverting > SPARK-7092 in the mean time. -- 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
