Note

If you get a Too many requests error, you are on the Cloudant Lite plan. The only way to raise limits, is to upgrade your Cloudant plan.

Note

If you get an error that a library is missing, install the cloudant-spark library. This is a manual one-time step that requires a kernel restart. Download the cloudant-spark jar for your Spark version.

For Spark 1.6: https://github.com/cloudant-labs/spark-cloudant/releases/download/v1.6.4/cloudant-spark-v1.6.4-167.jar…

For Spark 2.0: https://github.com/cloudant-labs/spark-cloudant/releases/download/v2.0.0/cloudant-spark-v2.0.0-185.jar

Then create a directory named jars under the home directory with mkdir jars. Copy the cloudant-spark jar file into the newly created directory. Then locate kernel.json file under the directory listing by running command jupyter pixiedust list. Edit kernel.json file and update the variable PYSPARK_SUBMIT_ARGS under env by adding –jars <local_home_directory>/jars/cloudant-spark.jar. "PYSPARK_SUBMIT_ARGS": "--jars /Users/USERNAME/jars/cloudant-spark-v1.6.4-167.jar ....
