In this tutorial we will discuss about structure of Linear regression and how a Linear regression Equation is constructed for 2 variable model.
This Tutorial talks about basics of Linear regression by discussing in depth about the concept of Linearity and Which type of linearity is desirable.
This was a research paper that we submitted to ICAPADS-2012 an IEEE – Institute of High performance distributed computing conference . It talks about a map reduce based solution to maze traversal problem which is applicable in many practical problems.
In the last article Sqoop : Hadoop : Importing data from RDBMS to HDFS we explored basic feature of importing the data in HDFS using Sqoop. In this article we will try to explore other very important tools that Sqoop provides.
In this article we will go through a very important technique – importing data from SQL table to HDFS. We will do so on a sample database say ‘bigdata’ and a sample table say ’employee’ containing employee data.
We will do this in 3 parts. Part 1 will be in scope of this article. We will look at the next parts in subsequent article
In this hadoop tutorial we will have a look at the modification to our previous program wordcount with our own custom mapper and reducer by implementing a concept called as custom record reader. Before we attack the problem let us look at some theory required to understand the topic.
