Hello there, I 'm following this tut to connect Elasticsearch and Spark:
I use command:
setx PYSPARK_DRIVER_PYTHON ipython
setx PYSPARK_DRIVER_PYTHON_OPTS notebook
pyspark ----driver-class-path /path-to-jar-file...
Everything is fine. But I don't want to connect to Spark server very more. Maybe I can only:
setx PYSPARK_DRIVER_PYTHON ipython
setx PYSPARK_DRIVER_PYTHON_OPTS notebook
setx SPARK_CLASSPATH /path-to-all-jar-files...
pyspark ----driver-class-path SPARK_CLASSPATH
But all are not run. Error:
Py4JJavaError: An error occurred while calling o139.save.
: java.lang.ClassNotFoundException: Failed to find data source: es. Please find packages at Third-Party Projects | Apache Spark
