Why Spark is Better than Hadoop

I have been creating videos related to Hadoop and spark from some time now. So as part of the series i am sharing video about why spark is better than Hadoop. As part of this video i have explained follwoing

 1. How spark avoids creating jvms again and again. Spark reuses the resources
2. Caching in spark
3. When spark gives far more faster results than Hadoop.
4. Code in spark is very compact

 It must be noted that there are lot of cases when Hadoop is better than spark. 
I hope you will like the video.

Please subscribe to my channel. Please also let us know. what are some other topics that you want a video on.

Hive UDF Example

UDF(User Defined Function) is a Very important functionality provided by Hive. It is very simple to create a UDF for Hive. In this tutorial we will learn creating UDF and how to use it with hive. There are two possible ways to create UDF. 1. using org.apache.hadoop.hive.ql.exec.UDF 2. using  org.apache.hadoop.hive.ql.udf.generic.GenericUDF        If input and output to your custom function is basic type eg. Text, FloatWritable, DoubleWritable,IntWritable etc the use  org.apache.hadoop.hive.ql.exec.UDF.        If yor input and output can be Map, set, list type of data structure the use  using  org.apache.hadoop.hive.ql.udf.generic.GenericUDF. We will discuss the first type of UDF here. I will write one more post to discuss the second approach. First of all lets assume I want to create a hive function called toUpper which will convert a string to uppercase. Follow the following steps to achieve it. 1. Download and install eclipse from  here 2. Hive should be installed, if

Custom UDF in Apache Spark

Image
Apache Spark has become very widely used framework to build Big data application. Spark SQL has made adhoc analysis on structured data very easy, So it is very popular among users who deal with huge amount of structured data. However many times you will realise that some functionality is not available in Spark SQL. For example in Spark 1.3.1 , when you are using sqlContext basic functions like variance , standard deviation and percentile are not available(You can access these using HiveContext). In a similar situation, you may like to do some string operation on an input column but functionality may not be available in sqlContext. In such situations , we can use spark udf to add new constructs in sqlContext. I have found them very handy, specially while processing string type columns. In this post we will discuss how to create UDFs in Spark and  how to use them. Use Case : Let us keep this example very simple. We will create a udf which will take a string as input and it will conve

Hadoop series : Pseudo Distributed Mode Hadoop Instalation

In this tutorial, we will learn required steps of setting up Hadoop on single node also called pseudo distributed mode. How ever as part of this series we will also setup hadoop on multiple machines. We will also learn Map Reduce, hive , Pig etc.So stay tuned, Here it comes .... :) We need Following this to start with. Ubuntu: I always prefer ubuntu as my linux flavour. However if you are using a very low end machine with very small ram, you can install Lubuntu also. Lubuntu is very light weight and any low end machine should work. If you have a windows machine. you can install hadoop using cygwin or VirtualBox or Vmware player.  Here we go... Steps for installation of Hadoop. If you are using Windows follow steps from 1 to 4 1. Download  and install Virtual box from https://www.virtualbox.org/wiki/Downloads   2. Download ubuntu from  http://www.ubuntu.com/download/desktop . If you have low  configuration machine then you can use Lubuntu. download Lubuntu from
