Need to know if there is any impact on storage or any other component when I decide to delete an HDI Cluster.
Welcome to the Microsoft Q&A platform.
Yes, you can delete HDInsight cluster when there is no use of compute resources for processing data. And there will be no impact on storage or any other components.
Azure HDInsight follows a strong separation of compute and storage-- as such the recommendation is to store your data either in Azure Storage blobs and Azure Data Lake Store, or a combination of the two. Both provide an HDFS compatible file system that persists data even if the cluster is deleted.
The benefit of this approach is:
The data is persistent, even after you delete your HDInsight cluster. This means it will also be available without any data transfer effort should you deploy a new cluster to perform additional processing.
The costs for storing your data are predominalty driven by the volume of data stored and tranferred, which can be signficantly less than the costs for running a cluster.
The data is available for multiple clusters to act upon.
Hope this will help. Please let us know if any further queries.
