Assignment Task

 

Assignment Overview
In this assignment, you are asked to write a report to describe how the following tasks are done.
(1) Fragment the tweet objects in 4tweets.json and distribute the fragments in the specified Hadoop nodes.
(2) Write Map/Reduce algorithms to compute query results for the query you select.
(3) Design Hbase tables to store the tweet objects in HBase.
(4) Write an Hbase algorithm to compute query result in Habse.

This type of report supplies critical information to help an organization to understand and decide whether a new system like Hadoop or Hbase is suitable for its business. This assignment aims to conduct analysis for this purpose.

The materials that you use include Week8 lecture slides, Week9 tutorial, the recommended videos, and other internet resources and/or books that you can find. Note that you must NOT copy these materials; otherwise, you commit plagiarism and the university formal plagiarism procedure will apply.
You complete the assignment together with two other students whom you choose yourself (in groups of three). If you do the assignment by your own or in a group of two, you still complete all tasks correctly to get full marks.

You must complete the tasks described in the next section in order. Otherwise, your discussion and references will be ambiguous.
Make sure that the file people.txt is edited to have correct information.
One submission from a group is sufficient for all group members to receive marks. Group members receive same marks unless the group has an alternative agreement.

-Now you try the Hbase way of storing the same twitter data set twitterdata in this task and computing query result in the next task. Note that the Hbase way is alternative to, not part of the Hadoop method.

  • Design Htables to store the data in twitterdata. You have the flexibility to use one Htable or multiple Htables as far as all the information of tweets is stored somewhere. Make sure that you understand the logic schema of a Htable in the slides before you do the design.
  • Each Htable has a row key, and one or more column families which you design. You do not need to consider timestamps and regions.
