Re: spark-shell :javap fails with complaint about JAVA_HOME, but it is set correctly

[Shixiong Zhu]

Scala 2.10 REPL javap doesn't support Java7 or Java8. It was fixed in Scala
2.11. See https://issues.scala-lang.org/browse/SI-4936

spark-shell :javap fails with complaint about JAVA_HOME, but it is set correctly

[Robert Dodier]

Hi,

I am working with Spark 1.5.1 (official release), with Oracle Java8,
on Ubuntu 14.04. echo $JAVA_HOME says "/usr/lib/jvm/java-8-oracle".

I'd like to use :javap in spark-shell, but I get an error message:

scala> :javap java.lang.Object
Failed: Could not load javap tool. Check that JAVA_HOME is correct.

However ls $JAVA_HOME/lib/tools.jar shows that it is there.

I tried starting spark-shell with -toolcp $JAVA_HOME/lib/tools.jar but
I get the same error.

For comparison, if execute scala and enter :javap java.lang.Object, it
works as expected.

Not sure where to go from here. Thanks for any advice.

best,

Robert Dodier
