  HBase workflow in this case is split in the domain lookup using row keys followed by status code filtering performed on the resulting dataset in Spark. The above result thus suggests that the first part of the run is fast enough to counteract poor follow-up performance involving filtering (must use full payload).

  The component we developed takes a line delimited list of URLs in a text file as input and reads them as a Spark Resilient Distributed Dataset. The HTML content is then fetched in parallel. While ideally the Spark application would read URLs directly from our class HBase table, bugs in the Spark methods to handle HBase reading as well as time ...

  Spark is built on top of the Hadoop MapReduce framework to provide an extension to it based on its basic primitive, the Resilient Distributed Dataset (RDD). The main idea behind RDDs is that they are immutable collections of statically typed objects spread across a Hadoop cluster.

  The main abstraction Spark provides is a resilient distributed dataset (RDD), which is a collection of elements partitioned across the nodes of the cluster that can be operated on in parallel. RDDs are created by starting with a file in the Hadoop file system (or any other Hadoop-supported file system), or an existing Scala collection in the ...
