-----------------------------------
Labels: pull-request-available (was: )
> [SHELL] spark-shell NPE: REPL cannot resolve Spark classes after SPARK-52587
> ----------------------------------------------------------------------------
>
> Key: SPARK-56447
> URL: https://issues.apache.org/jira/browse/SPARK-56447
> Project: Spark
> Issue Type: Bug
> Components: Spark Shell
> Affects Versions: 4.1.1
> Reporter: Eric Yang
> Priority: Major
> Labels: pull-request-available
>
> *Problem*
> Built on top of the latest code, spark-shell fails with:
> {code:java}
> Failed to initialize compiler: object scala in compiler mirror not found.
> ** Note that as of 2.8 scala does not assume use of the java classpath.
> ** For the old behavior pass -usejavacp to scala, or if using a Settings
> ** object programmatically, settings.usejavacp.value = true.
> Exception in thread "main" java.lang.NullPointerException: Cannot throw
> exception because "null" is null
> at
> scala.tools.nsc.CompilationUnits$CompilationUnit.<init>(CompilationUnits.scala:43)
> at
> scala.tools.nsc.CompilationUnits$CompilationUnit.<init>(CompilationUnits.scala:44)
> at
> scala.tools.nsc.interpreter.IMain$ReadEvalPrint.compile(IMain.scala:734)
> {code}
> while explicitly: `bin/spark-shell -usejavacp` can bring it back to work.
