Static Storage vs Heap vs Stack

The following is the summary of compiler storage allocation. 1. Static vs Dynamic Static: Storage can be made by compiler looking only at the text of the program. One reason for statically allocating as many data objects as possible is that the addresses of these objects can be compiled into target code. Dynamic: Storage can […]

What’s Next for Apache Hadoop Data Management and Governance

Hadoop – the data processing engine based on MapReduce – is being superceded by new processing engines: Apache Tez, Apache Storm, Apache Spark and others. YARN makes any data processing future possible. But Hadoop the platform – thanks to YARN as its architectural center – is the future for data management, with a selection of […]

The Importance of Apache Drill to the Big Data Ecosystem

You might be wondering what bearing a history lesson may have on a technology project such as Apache Drill. In order to truly appreciate Apache Drill, it is important to understand the history of the projects in this space, as well as the design principles and the goals of its implementation. The lessons that have been […]

SQOOP

How SQOOP-1272 Can Help You Move Big Data from Mainframe to Apache Hadoop

Apache Sqoop provides a framework to move data between HDFS and relational databases in a parallel fashion using Hadoop’s MR framework. As Hadoop becomes more popular in enterprises, there is a growing need to move data from non-relational sources like mainframe datasets to Hadoop. Following are possible reasons for this: HDFS is used simply as an […]

Kudu: New Apache Hadoop Storage for Fast Analytics on Fast Data

The set of data storage and processing technologies that define the Apache Hadoop ecosystem are expansive and ever-improving, covering a very diverse set of customer use cases used in mission-critical enterprise applications. At Cloudera, we’re constantly pushing the boundaries of what’s possible with Hadoop—making it faster, easier to work with, and more secure. Cloudera, the […]

Introduction to HDFS Erasure Coding in Apache Hadoop

Hadoop is a popular open-source implementation of MapReduce framework designed to analyze large data sets. It has two parts; Hadoop Distributed File System (HDFS) and MapReduce. HDFS is the file system used by Hadoop to store its data. It has become popular due to its reliability, scalability, and low-cost storage capability. HDFS by default replicates […]

Drill into Your Big Data Today with Apache Drill

Big data techniques are becoming mainstream in an increasing number of businesses, but how do people get self-service, interactive access to their big data? And how do they do this without having to train their SQL-literate employees to be advanced developers? One solution is to take advantage of the rapidly maturing open source, open community […]

Hadoop-Cluster

How-to: Deploy Apache Hadoop Clusters Like a Boss

The HDFS docs have some information, and logically it makes sense to separate the network of the Hadoop nodes from a “management” network. However, in our experience, multi-homed networks can be tricky to configure and support. The pain stems from Hadoop integrating with a large ecosystem of components that all have their own network and […]

Template Method Design Pattern in Java

Template Method is a behavioral design pattern and it’s used to create a method stub and deferring some of the steps of implementation to the subclasses. Template method defines the steps to execute an algorithm and it can provide default implementation that might be common for all or some of the subclasses. Template means Preset format like HTML templates which […]

Spring provides some features which are not available in struts 2.Most powerful among them is dependency injection.To learn more about dependency injection,you can refer dependency injection in spring link. Create project named “Struts2Spring3IntegrationExample”. First of all, you need […]

Listeners: Can Java Hear You?

What Sort of Listener Are You? If we tried to implement a full graphical interface in a program by using MouseListener, we’d have a lot of work to do. We’d have to draw all the buttons using drawing instructions in our program, then wait for mouse clicks. Once we got a click on something we’d […]

Java’s Inner Classes: The Keys to the Kingdom

An inner class is a Java class that’s defined inside another class. In both the examples above, I have a class called VGKernel, which is the class that implements the video game kernel. Inside that class, I define other classes. This has a special effect on the relationship between those classes and VGKernel. Normally, our […]

Java Video Game Programming: Game Logic

CodeSpells, an immersive, first-person player video game designed to teach students in elementary to high school how to program in the popular Java language, has been developed by University of California, San Diegocomputer scientists. In simple video games, there is usually some object in the game that does most of the “thinking” with respect to the game’s rules. […]

Jackson example – Read and write JSON

Java JSON Processing API is not very user friendly and doesn’t provide features for automatic transformation from Json to Java object and vice versa. Luckily we have some alternative APIs that we can use for JSON processing. In last article we learned about Google Gson API and saw how easy to use it. Jackson project has implemented a very […]
