While trying to install the shell interpreter for zeppelin (v 0.8.0), I fail with this message: # sudo /usr/hdp/current/zeppelin-server/bin/install-interpreter.sh --name shell OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0 SLF4J: Class path contains multiple SLF4J bindings.

Hi, I'm following Douglas Eadline's tutorial http://www.informit.com/store/hadoop-and-spark-fundamentals-livelessons-9780134770864 and try to compile the WordCount example, but I fail. Eadline suggests to comile it with hadoop-core.jar, which was renamed in newer versions as I understand. I tried with javac -classpath /usr/hdp/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core.jar -d wordcount_classes WordCount.java but I still get a load of errors. Any suggestions? Where can I find the correct jar?
