With Spark you can read data from HDFS and submit jobs under YARN resource manager so that they would share resources with MapReduce jobs running in parallel (which might as well be Hive queries or Pig scrips, for instance). Hadoop, flexible and available architecture for large scale computation and data processing on a network of commodity hardware. A low latency query engine for Apache Hadoop that provides real-time or near real-time, ad hoc query capability, while completing batch-processing of MapReduce. In one embodiment, the low latency query engine comprises a daemon that is…
