Hadoop Likes Big Files

One of the frequently overlooked yet essential best practices for Hadoop is to prefer fewer, bigger files over more, smaller files. How small is too small and how many is too many? How do you stitch together all those small Internet of Things files into files “big enough” for Hadoop to process efficiently? The ProblemContinue reading “Hadoop Likes Big Files”

Create HDInsight Cluster in Azure Portal

Creating an HDInsight cluster from the Azure portal is very easy. However, sometimes you want all the choices and best practices explained as well as the “how to”. I have created a series of slides with audio recordings to walk you through the process and choices.

Azure Maximums and Resource Usage from PowerShell

Technorati Tags: Azure,PowerShell Have you ever struggled to find out how many VM cores, HDInsight cores, storage accounts, or other Azure resources your subscription is set to allow or how many you actually use? Maybe you want to use this information in your automation scripts to avoid trying to create components for which you don’tContinue reading “Azure Maximums and Resource Usage from PowerShell”

Use Additional Storage Accounts with HDInsight Hive

When you create an HDInsight Hadoop cluster you pass in one or more storage accounts and their associated keys. This allows you to access the files on all associated storage accounts from the cluster. If you want to use public storage that isn’t passed in at create time that’s easy – simply supply the storageContinue reading “Use Additional Storage Accounts with HDInsight Hive”

Getting Started with Azure PowerShell Cmdlets–Subscription Management

I’ve started using the Azure PowerShell cmdlets more often to manage virtual machines and HDInsight in Azure. Once you connect to a subscription everything just works. However, the initial steps to get one or more subscriptions configured to be used from your machine or understanding how to change subscription information on your machine can beContinue reading “Getting Started with Azure PowerShell Cmdlets–Subscription Management”

Sample PowerShell Script: HDInsight Custom Create

For a really reproducible, automated environment you would want to put this into a .ps1 script that accepts parameters (see here for an example). However, you may find the method below good for learning and experimenting. Replace all the “YOURxyz” sections with yourContinue reading “Sample PowerShell Script: HDInsight Custom Create”

PowerShell for Azure cmdlets: Subscription was all Wacky

I was working on some HDInsight scripts in PowerShell and doing lots of experimenting. I’m not sure what exactly I did but all of a sudden everything stopped working. With lots of interruptions from meetings and chats and lunch…. I couldn’t retrace my steps. Everything seemed to fail on the Azure subscription information so IContinue reading “PowerShell for Azure cmdlets: Subscription was all Wacky”
