The Hortonworks Blog

Posts categorized by : HCatalog

The last couple of weeks have been a period of intense activity around the Apache projects that comprise the Hadoop ecosystem. While most of the headlines were accorded to Apache Hadoop 2 going GA, it would be remiss not to pay attention to the great progress being made in the Apache projects that complement Hadoop.

We have blogged about these over the course of the past week and the list below provides a quick summary of the phenomenal work contributed in the open by the folks driving these diverse and vital communities.…

Microsoft has begun to treat its developer community to a number of Hadoop-y releases related to its HDInsight (Hadoop in the cloud) service, and it’s worth rounding up the material. It’s all Alpha and Preview so YMMV but looks like fun:

  • Microsoft .NET SDK for Hadoop. This kit provides .NET API access to aspects of HDInsight including HDFS, HCatalag, Oozie and Ambari, and also some Powershell scripts for cluster management. There are also libraries for MapReduce and LINQ to Hive.

The end of another action-packed week and just before we all head off for the weekend then let’s have a recap on the conversations from this week – we hope you’re enjoying them.

We’re delighted by the response to our Hadoop Patterns of Use whitepaper and presentation - that really seems to have struck a chord with everyone thinking about what Hadoop can really do for their business. You can see that content just below here – an excellent read for the journey home.…

Unstructured data, semi-structured data, structured data… it is all very interesting and we are in conversations about big and small versions of each of these data types every day. We love it…  we are data geeks at Hortonworks. We passionately understand that if you want to use any piece of data for some computation, there needs to be some layer of metadata and structure to interact with it.  Within Hadoop, this critical metadata service is provided by HCatalog.…

According to the Transaction Processing Council, TPC-H is:

The TPC Benchmark™H (TPC-H) is a decision support benchmark. It consists of a suite of business oriented ad-hoc queries and concurrent data modifications. The queries and the data populating the database have been chosen to have broad industry-wide relevance. This benchmark illustrates decision support systems that examine large volumes of data, execute queries with a high degree of complexity, and give answers to critical business questions.…

Go from Zero to Big Data in 15 Minutes!

Today Hortonworks announced the availability of the Hortonworks Sandbox, an easy-to-use, flexible and comprehensive learning environment that will provide you with fastest on-ramp to learning and exploring enterprise Apache Hadoop.

The Hortonworks Sandbox is:

  • A free download
  • A complete, self contained virtual machine with Apache Hadoop pre-configured
  • A personal, portable and standalone Hadoop environment
  • A set of hands-on, step-by-step tutorials that allow you to learn and explore Hadoop on your own

The Hortonworks Sandbox is designed to help close the gap between people wanting to learn and evaluate Hadoop, and the complexities of spinning up an evaluation cluster of Hadoop.…

Today our partner, Teradata, announced availability of the Teradata Aster Big Analytics Appliance, which packages our Hortonworks Data Platform (HDP) with Teradata Aster on machine that is ready to plug-in and bring big data value in hours.

There is more to this appliance than meets the eye…  it is not just a simple packaging of software on hardware. Teradata and Hortonworks engineers have been working together for months tying our solutions together and optimizing them for an appliance.…

Alan Gates presented HCatalog to the Chicago Hadoop User Group (CHUG) on 9/17/12. There was a great
turnout, and the strength of CHUG is evidence that Chicago is a Hadoop city. Below are some kind words from the host, Mark Slusar.

On 9/17/12, the Chicago Hadoop User Group (CHUG) was delighted to host Hortonworks Co-Founder Alan Gates to give an overview of HCatalog. In addition to downtown Chicago meetups, Allstate Insurance Company in Northbrook, IL hosts regular Chicago Hadoop User Group Meetups.…

Representatives from Twitter, Yahoo, LinkedIn, Hortonworks and IBM met at Twitter HQ on Thursday to talk HCatalog. Committers from HCatalog, Pig and Hive were on hand to discuss the state of HCatalog and its future.

Apache HCatalog is a table and storage management service for data created using Apache Hadoop.

A central theme was using HCatalog to enable sharing and use of legacy data and diverse formats like TSV, JSON, RCFile, Protobuf, Thrift and Avro, among diverse tools like Pig, Hive, Cascading, SQL-H and JAQL.…

Series Introduction

Hortonworks is on a mission to accelerate the development and adoption of Apache Hadoop. Through engineering open source Hadoop, our efforts with our distribution, Hortonworks Data Platform (HDP), a 100% open source data management platform, and partnerships with the likes of Microsoft, Teradata, Talend and others, we will accomplish this, one installation at a time.

What makes this mission possible is our all-star team of Hadoop committers. In this series, we’re going to profile those committers, to show you the face of Hadoop.…

Series Introduction

This is part three of a series of blog posts covering new developments in the Hadoop pantheon that enable productivity throughout the lifecycle of big data.  In a series of posts, we’re exploring the full lifecycle of data in the enterprise: Introducing new data sources to the Hadoop filesystem via ETL, processing this data in data-flows with Pig and Python to expose new and interesting properties, consuming this data as an analyst in Hive, and discovering and accessing these resources as analysts and application developers using HCatalog and Templeton.…

If you haven’t yet noticed, we have made Hortonworks Data Platform v1.0 available for download from our website. Previously, Hortonworks Data Platform was only available for evaluation for members of the Technology Preview Program or via our Virtual Sandbox (hosted on Amazon Web Services). Moving forward and effective immediately, Hortonworks Data Platform is available to the general public.

Hortonworks Data Platform is a 100% open source data management platform, built on Apache Hadoop.…

I wanted to take this opportunity to share some important news. Today, Hortonworks announced version 1.0 of the Hortonworks Data Platform, a 100% open source data management platform based on Apache Hadoop. We believe strongly that Apache Hadoop, and therefore, Hortonworks Data Platform, will become the foundation for the next generation enterprise data architecture, helping companies to load, store, process, manage and ultimately benefit from the growing volume and variety of data entering into, and flowing throughout their organizations.…

The following press release was issued by Hortonworks today.
