Thanks for the update. I hadn’t even seen the ‘SPARK_DIST_CLASSPATH’ setting until just now, but I suspect for CDH that might be the only way to do it. The reason for the class path errors you see is that the ‘client’ JAR on its own ships a few extra dependencies (i.e. com.fasterxml.jackson) which are incompatible with newer versions of Spark. The ‘client-spark’ JAR attempts to remove those dependencies which would conflict with Spark, although a more elegant solution will likely come with PHOENIX-2535 ( https://issues.apache.org/jira/browse/PHOENIX-2535) Re: speed, the spark integration should be just about as fast as the MapReduce and Pig integration. At the 3T level, your likely bottleneck is disk IO just to load the data in, although network IO is also a possibility here as well. Assuming you have a sufficient number of Spark workers with enough RAM allocated, once the data is loaded into Spark initially, operations on that dataset should proceed much faster, as much of the data will be available in RAM vs disk.
