Explanation of Solution

Hadoop:

  • “Hadoop” is a Java based, open source software framework that is used for distributed storage and distributed processing of large data sets.
  • Open source means, it is freely available and the source code can be changed according to users requirements.
  • Hadoop uses low-cost hardware that can create clusters of thousands of computer nodes to store and process data.
  • Hadoop was developed by Google to work on distributed file systems and parallel processing, which is now supported by Apache Software Foundation.

Components of Hadoop:

The main components of Hadoop are Hadoop Distributed File System (HDFS), MapReduce, and YARN (Yet Another Source Negotiator).

Hadoop Distributed File System (HDFS)

  • Hadoop Distributed File System (HDFS) is a component of Hadoop that is used to store large amounts of data of various formats running on a cluster at high speeds.
  • It usually works on the principle of storing less number of large files rather than huge number of small files.
  • HDFS uses the write-once, read many model to achieve high throughput...

Dijkstra's Algorithm (part 1).  Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values.  Write down your final [correct] answer, as you‘ll need it for the next question.
