I have a storage account,
democluster
, and a default container,
democlustercontainer
. You may need to
replace these values with your own.
Note
There is also a way to emulate Azure blob storage in your local machine where you have installed the HDInsight
emulator. You can use
Windows Azure Storage Emulator
to emulate the Windows Azure Storage blob (WASB)
table and queue cloud services on your local machine. Doing so helps you in getting started with basic testing and
evaluation locally without incurring the cost associated with cloud service. The Windows Azure Storage emulator
comes as a part of Windows Azure SDK for .NET. This topic, however, does not use the storage emulator, rather it uses
actual WASB as HDInsight storage. Detailed instructions on configuring the storage emulator to be used from the
HDInsight emulator can be found at:
http://www.windowsazure.com/en-us/documentation/articles/hdinsight-get-started-emulator/#blobstorage
The emulator also deploys the same set of Windows Services as the Azure service. You can open up the Windows
Services console from Start
➤
Run
➤
Services.msc to start, stop, and set the startup type of the Apache Hadoop
services as shown in Figure
7-8
