La última semana tuve la oportunidad de contar la experiencia de Socialmetrix instalando y configurando clusters de Datastax Analytics en Azure. Datastax brinda una solución comercial en un bundle, conteniendo Cassandra, Spark y Solr integrados. Las charlas se dieron en Argentina Big Data Meetup. Hosted by Jampp y el Nardoz Meetup. Hosted by Medallia

We have been using Spark Standalone deploy for more than one year now, but recently I tried to use Azure’s HDInsight which runs on Hadoop 2.6 (YARN deploy).

After provisioning the servers, all small tests worked fine, I have been able to run Spark-Shell, read and write to Blob Storage, until I tried to write to Datastax Cassandra cluster which constantly returned a error message: Exception in thread "main" java.io.IOException: Failed to open native connection to Cassandra at {10.0.1.4}:9042
