Eric Yang created SPARK-56447:
---------------------------------
Summary: [SHELL] spark-shell 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
*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.interpreter.IMain$ReadEvalPrint.compile(IMain.scala:734) {code}
while explicitly: `bin/spark-shell -usejavacp` can bring it back to work.
