SPARK is Replacement for MapReduce in Bigdata Real Analytics!

Apache Spark is among the Hadoop ecosystem technologies acting as catalysts for broader adoption of big data infrastructure. Now, Looker -- a vendor of business intelligence software -- has announced support for Spark and other Hadoop technologies. The goal? To speed up access to the data that fuels business decision making.
SPARK Vs MapReduce
SPARK Jobs

Hadoop's arrival on the scene 10 years ago may have started the big data revolution, but only recently did adoption of this technology begin spreading to a wider audience. Apache Spark is one of the catalysts for the growing adoption rates.

Spark can be used as a replacement for MapReduce, a component of Hadoop implementations, to speed up the processing and analytics of big data by 100x in memory, according to the Apache Software Foundation.

In today's business environment, in which real-time analytics is the goal and organizations don't want to wait for data warehouses and analysts to provide batch intelligence back to business users, Spark has gained momentum.

And here's one case in point: Looker, a business intelligence platform used by Avant, Acorns, and Etsy, this week announced support for Presto and Spark SQL. The company also updated its support for Impala and Hive, other Hadoop ecosystem technologies that speed up analysis on Hadoop.

Looker's announcement of support for these additional Hadoop ecosystem technologies lets organizations "leave data in Hadoop and process it at speed and at scale," said James Haight,

Automation developer these are top Skills you need to learn

By
Robotic process automation is an upcoming IT skill. Three tools are popular. It is difficult to learn all three tool. So, learn anyone tool to start your career in automation.
To get a job in this line, I found in my research that some programming skills and Hand-on training on any one of the tools is required. Also, try to know the differences between popular RPA tools.
Skills Companies Looking in Automation Engineers All big companies looking for candidates having experience in Automation anywhere, Blue Prism and UIPath. It is not possible to learn all tools. Learn anyone tool and do practice well.

Ok.

You may ask a question about how to do it. Join in good training institute and learn one tool.  Take online classes to learn faster.

To learn Uipath try here. Also, you can enroll online course to learn UiPath.

Three popular RPA tools functional differences

By
Robotic process automation is growing area and many IT developers across the board started up-skill in this popular area. I have written this post for the benefit of Software developers who are interested in RPA also called Robotic Process Automation.


In my previous post, I have described that total 12 tools are available in the market. Out of those 3 tools are most popular. Those are Automation anywhere, BluePrism and Uipath. Many programmers asked what are the differences between these tools. I have given differences of all these three RPA tools.

BluePrism Blue Prism has taken a simple concept, replicating user activity on the desktop, and made it enterprise strength. The technology is scalable, secure, resilient, and flexible and is supported by a comprehensive methodology, operational framework and provided as packaged software.The technology is developed and deployed within a “corridor of IT governance” and has sophisticated error handling and process modelling capabilities to ens…

Top 100 Hadoop Complex Interview Questions (Part 3 of 4)

By
These are complex Hadoop interview questions. This is my 3rd set of questions useful for your interviews. 1). What are the features of Standalone (local) mode? Ans). In stand-alone mode there are no daemons, everything runs on a single JVM. It has no DFS and utilizes the local file system. Stand-alone mode is suitable only for running MapReduce programs during development. It is one of the least used environments.

2). What are the features of Pseudo mode?
Ans). The pseudo mode is used both for development and in the QA environment. In the Pseudo mode, all the daemons run on the same machine.

3). Can we call VMs as pseudos?
Ans). No, VMs are not pseudos because VM is something different and pseudo is very specific to Hadoop.

4). What are the features of Fully Distributed mode?
Ans). The fully Distributed mode is used in the production environment, where we have ‘n’ number of machines forming a Hadoop cluster. Hadoop daemons run on a cluster of machines. There is one host onto which Namenod…

SQL queries how to use built-in functions correctly

By
In this post I am giving top examples on SQL functions. About built-in functions, I have covered in my previous post.
List of examples:DATE-TIME functionsNumeric functionsChar functionsNull-related functions1. DATE/TIME functions SELECT p_code, launch_dt, CURRENT_DATE FROM product; CURRENT_DATE returns current date.
SELECT p_code, TO_CHAR(launch_dt, 'DD MONTH YYYY') reformatted_dt FROM product; TO_CHAR function returns DATE in CHAR format.
2. Numeric functions SELECT p_code, price, (price - 20), ABS(price - 20.00) FROM product; ABS - function returns absolute value
SELECT p_code, price, ROUND (price, 1) FROM product;
ROUND function - Round to 1 digit.
SELECT p_code, price, SIGN(price - 15) FROM product;
SIGN function - It returns sign; either + or -
SELECT p_code, price, TRUNC(price, 1) FROM product;
TRUNC function - Truncates to a certain number of decimal places.
