https://github.com/apache/zeppelin/pull/2709
In this PR a change was made to `bin/interpreter.sh` script. In line 124
`SPARK_APP_JAR="$(ls
${ZEPPELIN_HOME}/interpreter/spark/spark-interpreter*.jar)"` used to be
`SPARK_APP_JAR="$(ls ${ZEPPELIN_HOME}/interpreter/spark/zeppelin-spark*.jar)"`
This change was not updated in `bin/interpreter.cmd`, meaning that spark
interpreter fails in windows.---
