I defined SPARK_EXECUTOR_URI when starting the zeppelin. I got "pyspark is not responding" when using %pyspark
Traceback (most recent call last): File "/tmp/zeppelin_pyspark.py", line 20, in <module> from py4j.java_gateway import java_import, JavaGateway, GatewayClient ImportError: No module named py4j.java_gateway Please let me know what to do to work around the issue. Thanks.
