Creating Azure HDinsight Spark cluster with ADLS Gen 2,Userassigned managed idnetity with StorageBlobdataOwner role.
Successfully assigned msi role to storage but getting error with HDInsight deployment(Internal server error)
Theres some issue with HDInsight(Storage profile)resource code in the template i think.

    Hello @Anon4914 ,

    Update: Ensure that your storage account has the user-assigned identity with Storage Blob Data Contributor role permissions, otherwise cluster creation will fail.

    If you are using Azure Data Lake Storage Gen2 and receive the error AmbariClusterCreationFailedErrorCode: "Internal server error occurred while processing the request. Please retry the request or contact support.".

    To resolve this issue, open the Azure portal, go to your Storage account, and under Access Control (IAM), ensure that the Storage Blob Data Contributor or the Storage Blob Data Owner role has Assigned access to the User assigned managed identity for the subscription. See Set up permissions for the managed identity on the Data Lake Storage Gen2 account for detailed instructions.

    Make sure you have followed the necessary steps to configure a Data Lake Storage gen2 account.

    Reference: Use Azure Data Lake Storage Gen2 with Azure HDInsight clusters

    Hope this helps. Do let us know if you any further queries.
