Will Berkeley created KUDU-2485:
-----------------------------------
Summary: Enhance Kudu-Spark docs
Key: KUDU-2485
URL: https://issues.apache.org/jira/browse/KUDU-2485
Project: Kudu
Issue Type: Improvement
Components: spark
Affects Versions: 1.7.1
Reporter: Will Berkeley
Users often get confused about the right way to use the Kudu-Spark integration.
The most common dangerous result is that they create multiple Kudu clients,
sometimes even one per task. It's pretty easy to overwhelm the master in this
way, e.g., with a 2 second batch window and a client per task in a Spark
streaming job. We should take our current minimal Spark docs and provide better
examples and bigger, louder, redder warnings about making extra Kudu clients.
Users should be directed to use the KuduContext exclusively. When a client is
needed, the client instance inside the KuduContext should be used.
