What is Apache Spark<\/span><\/h2>\n<\/div>\n<\/div>\n
\n
\n
    \n
  • Apache Spark is an open-source distributed cluster-computing framework.<\/li>\n
  • Spark is a data processing engine developed to provide faster and ease-of-use analytics than Hadoop MapReduce.<\/li>\n
  • Before Apache Software Foundation took possession of Spark, it was under the control of University of California, Berkeley\u2019s AMP Lab.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n

    \n

    What is Apache Hadoop<\/h2>\n<\/div>\n<\/div>\n
    \n
    \n
      \n
    • Apache Hadoop is an open-source framework written in Java that allows us to store and process Big Data in a distributed environment, across various clusters of computers using simple programming constructs.<\/li>\n
    • To do this, Hadoop uses an algorithm called MapReduce, which divides the task into small parts and assigns them to a set of computers.<\/li>\n
    • Hadoop also has its own file system, Hadoop Distributed File System (HDFS), which is based on the Google File System (GFS).<\/li>\n
    • HDFS is designed to run on low-cost hardware.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
