spark sbt编译错误库

Question

1.2.0-bin-hadoop2.4 and my Scala version is 2.11.7 . I am getting an error so I can't use sbt.

~/sparksample$ sbt

Starting sbt: invoke with -help for other options [info] Set current project to Spark Sample (in build file:/home/beyhan/sparksample/)

> sbt compile

Any suggestions? Thanks

Answer 1

There exists no spark-core_2.11.7 jar file. You have to get rid of the maintenance version number .7 in the spark dependencies because spark-core_2.11 exists. All Scala versions with version 2.11 should be compatible.

Update

A minimal sbt file could look like

name := "Simple Project"

version := "1.0"

scalaVersion := "2.11.7"

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.1"

Answer 2

As @Till Rohrmann suggested you there's no such thing as spark-core_2.11.7 and your build.sbt appears to reference that library.

I suggest you to edit the file /home/beyhan/sparksample/build.sbt and remove the references to that library.

The correct reference is:

libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "1.2.0"

Remember that not only spark-core does not have any version 2.11.7 but also other spark libraries that you might be using.
