 When you provision an HDInsight cluster, you specify an Azure Storage account. A specific blob container from that account is designated as the default file system, like in the Hadoop distribute file system (HDFS). By default, the HDInsight cluster is provisioned in the same datacenter as the storage account you specify.

 In addition to this storage account, you can add additional storage accounts when you custom configure an HDInsight cluster. This additional storage account can be from the same Azure subscription or from different Azure subscriptions. For instructions, see [Provision HDInsight clusters using custom options][hdinsight-provision]. 
 
 To simplify this tutorial, only the default blob and the default storage account are used. In practice, the data files are usually stored in a designated storage account.

 Low-cost Azure Blob storage is a robust, general-purpose, Hadoop-compatible storage solution that integrates seamlessly with HDInsight. Through a Hadoop distributed file system (HDFS) interface, the full set of components in HDInsight can operate directly on data in Azure Blob storage. In this tutorial, learn how to set up a container for blob storage, and then address the data inside.

 Wherever it lives, each blob you create belongs to a container in your Azure Storage account. This container may be an existing blob that was created outside of HDInsight, or it may be a container that is created for an HDInsight cluster. 
 
+Don't share a default storage container with multiple HDInsight clusters. If you need to use a shared container to provide access to data for multiple HDInsight clusters then you should add it as an additional storage account in the cluster configuration. For more information, see [Provision HDInsight clusters][hdinsight-provision]. However you can reuse a default storage container after the original HDInsight cluster has been deleted. For HBase clusters, you can actually retain the HBase table schema and data by provision a new HBase cluster using the default blob storage container that is used by an HBase cluster that has been deleted.
