What’s New in Kite SDK 0.15.0?

Kite SDK’s new release contains new improvements that make working with data easier.

Recently, Kite SDK, the open source toolset that helps developers build systems on the Apache Hadoop ecosystem, became a 0.15.0. In this post, you’ll get an overview of several new features and bug fixes.

Working with Datasets by URI

How-to: Use Kite SDK to Easily Store and Configure Data in Apache Hadoop

Organizing your data inside Hadoop doesn’t have to be hard — Kite SDK helps you try out new data configurations quickly in either HDFS or HBase.

Kite SDK is a Cloudera-sponsored open source project that makes it easier for you to build applications on top of Apache Hadoop. Its premise is that you shouldn’t need to know how Hadoop works to build your application on it, even though that’s an unfortunately common requirement today (because the Hadoop APIs are low-level; all you get is a filesystem and whatever else you can dream up — well, code up).

New Training: Design and Build Big Data Applications

Cloudera’s new “Designing and Building Big Data Applications” is a great springboard for writing apps for an enterprise data hub.

Cloudera’s vision of an enterprise data hub as a central, scalable repository for all your data is changing the notion of data warehousing. The best way to gain value from all of your data is by bringing more workloads to where the data lives. That place is Apache Hadoop.

How-to: Process Data using Morphlines (in Kite SDK)

Our thanks to Janos Matyas, CTO and Founder of SequenceIQ, for the guest post below about his company’s use case for Morphlines (part of the Kite SDK).

SequenceIQ has an Apache Hadoop-based platform and API that consume and ingest various types of data from different sources to offer predictive analytics and actionable insights. Our datasets are structured, unstructured, log files, and communication records, and they require constant refining, cleaning, and transformation.

Cloudera Development Kit is Now "Kite SDK"

CDK has a new monicker, but the goals remain the same.

We are pleased to announce a new name for the Cloudera Development Kit (CDK): Kite. We’ve just released Kite version 0.10.0, which is purely a rename of CDK 0.9.0.

Email Indexing Using Cloudera Search and HBase

In my previous post you learned how to index email messages in batch mode, and in near real time, using Apache Flume with MorphlineSolrSink. In this post, you will learn how to index emails using Cloudera Search with Apache HBase and Lily HBase Indexer, maintained by NGDATA and Cloudera. (If you have not read the previous post, I recommend you do so for background before reading on.)

Which near-real-time method to choose, HBase Indexer or Flume MorphlineSolrSink, will depend entirely on your use case, but below are some things to consider when making that decision:

Cascading, Spring, and Spark: Development Choices for CDH Users Expand

In software development, there is no substitute for having choices. Furthermore, freedom of choice – between frameworks, APIs, and languages — is a major fuel source for platform adoption across any successful ecosystem.

In the case of development on CDH, the open source core of Cloudera’s Big Data platform containing Apache Hadoop and related ecosystem projects, the choices have expanded dramatically in the past three weeks:

Collection Aliasing: Near Real-Time Search for Really Big Data

The rise of Big Data has been pushing search engines to handle ever-increasing amounts of data. While building Cloudera Search, one of the things we considered in Cloudera Engineering was how we would incorporate Apache Solr with Apache Hadoop in a way that would enable near-real-time indexing and searching on really big data.

Eventually, we built Cloudera Search on Solr and Apache Lucene, both of which have been adding features at an ever-faster pace to aid in handling more and more data. However, there is no silver bullet for dealing with extremely large-scale data. A common answer in the world of search is “it depends,” and that answer applies in large-scale search as well. The right architecture for your use case depends on many things, and your choice will generally be guided by the requirements and resources for your particular project.

Email Indexing Using Cloudera Search

Why would any company be interested in searching through its vast trove of email? A better question is: Why wouldn’t everybody be interested? 

Email has become the most widespread method of communication we have, so there is much value to be extracted by making all emails searchable and readily available for further analysis. Some common use cases that involve email analysis are fraud detection, customer sentiment and churn, lawsuit prevention, and that’s just the tip of the iceberg. Each and every company can extract tremendous value based on its own business needs. 

Next Stops for The Cloudera Sessions: Jersey City, Miami, Denver, Milwaukee

Cloudera Sessions

In its first leg of its tour of the United States earlier this year (see photos here), The Cloudera Sessions proved to be an invaluable single-day event for business and technical leaders exploring practical applications of Apache Hadoop. So valuable, in fact, that we’ve extended the tour with dates/cities this September and October.
