Slides: https://www.slideshare.net/DataStax/datastax-advanced-dse-analytics-client-configuration-jacek-lewandowski-cassandra-summit-2016 | DataStax Enterprise clients, such as CQLSH or Hadoop and Spark based applications, can be precisely configured to achieve a desired behaviour. For a basic use case, we just run a dedicated DSE command and do not care about how all of those pieces are setup to work together, leveraging the goodness of DSE. However, understanding where and what we need to modify to achieve the expected change in the configuration is essential for using DSE efficiently. In this presentation we go through the basic and advanced settings for client applications, including security features and limitations or DSE patches introduced into integrated Spark. We show the new tools which significantly simplify the configuration of external DSE installations which are used just for accessing DSE cluster in client mode. Finally, we conclude with hints for configuring Spark driver from scratch in order to use it in a web application, when running the program through DSE scripts is not feasible.
