The problem was having only 1 core instance as the logs were saved in HDFS so this instance became a bottleneck. I added another core instance and it's going much better now.

Another solution could be to save the logs to S3/S3A instead of HDFS, changing those parameters in spark-defaults.conf (make sure they are changed in the UI config too) but it might require adding some JAR files to work.

As it's unable to find driver class when you are running it from Jupyter Notebook, to avoid that you can try by copying mysql-connector-java-5.1.47.jar to the $SPARK_HOME/jars folder. It will resolve your driver issue as per my personal experience.

The "json_data" content is actually a string and not json which has built in schema structures like arrays, maps, and structs. My problem is with the extraneous double quotes (") around the actual guts of the "json_data" that was causing a problem when Spark was trying to read it. Sample:

It looks like an issue with the SerDe class.

Try to make use of this implementation: 'org.apache.hive.hcatalog.data.JsonSerDe' present in hive-hcatalog-core-0.13.0.jar;

This works for me.

Mapping column names in Hive with JSON serde

Asked 2017-Mar-01 at 18:34

I'm using the built-in JSON serde in Hive to create an external table, i.e. org.apache.hive.hcatalog.data.JsonSerDe. My input JSON contains a field called last, which I would like to map to a different column name in my table, since last is a reserved keyword.

Is this possible to do with SERDEPROPERTIES? I can find examples of how to do this with the OpenX Json serde, but not the hive one.

Currently I'm creating my table like this
