I have just created a Spark based HDInsight cluster. I have selected a blob storage that I created before, while creating the cluster. However, I have no idea how to access that blob storage from within the VM created there. I have read many different tutorials, but couldn't get a proper answer.
I can see that the default container's folders/files correspond to the HDFS directories in the VM. Is it possible to add the blob storage to the default container, so that I can also access it just like an HDFS directory?
You can access blobs using Azure PowerShell or Azure CLI with cmdlets.
Refer : Access blobs in Azure HDInsight.
If you want to access blobs using Azure Storage Explorer with GUI:

We need to create a shared storage account for Synapse and Databricks, however we can only use existing storage accounts in Synapse while Databricks creates separate resource groups on its own and there is no option to use existing one also why there the managed resource group created by databricks have locks in it?
There are two things regarding storage accounts & Databricks:
Databricks automatically creates a storage account for each workspace to hold so-called DBFS Root. This storage account is meant to be used to keep only temporary data, libraries, cluster logs, models, etc. It's not designed to keep the production data as this storage account isn't accessible outside of the Databricks workspace.
Databricks can work with storage accounts created outside of the workspace (documentation) - just create a dedicated storage account to keep your data, and access it using the abfss protocol as described in the documentation, or mount it into workspace (although it's not recommended anymore). And then you can access that storage account from Synapse & other tools as well.
I want to sync my file from network folder to Azure blob but without using azcopy. Basically I dont want command line to be a part of the process but it should perform simple direct sync from file to azure blob. (if one file updates or deletes , the other storage should also update automatically). Is it possible to do that?
• You can use the ‘Azure Storage Explorer’ software in this case. But before using the Azure storage explorer, I would recommend you to please ensure that the RBAC assignments are correctly assigned to the Azure AD members or people who will be accessing the Azure Storage Explorer software for this purpose.
Kindly find the below snapshots for your reference on the demonstrated possibility of blob files syncing through the Azure Storage explorer software: -
Storage explorer – 1: -
Azure Blob storage: -
Storage explorer – 2: -
Azure Blob storage: -
Deleted file in Azure storage explorer and the same in Blob storage: -
Thus, as you can see from the images above, the blob file synced from the Azure storage explorer is correctly synchronised from the local system to the Azure blob storage just by uploading the blob files from the local system through the Azure storage explorer to the blob container in Azure. Also, when you delete the selected file from Azure blob storage, it is synced automatically in the Azure storage explorer application and shown accordingly.
For more details on configuring the Azure storage account in the storage explorer, kindly refer the below documentation link: -

I'm moving some files from S3 to Azure Storage. I was using ACL per file in the S3 Account, so I had some private files and some public files in the same Bucket.
The problem is that I cannot find a way to set ACL per file in Azure Storage, I see I can set ACL in the container, but no in the Blob.
Is there a way to do this, or is not possible in Azure Storage?
Edit:
I ended up using one container for public files and one container for private files, that made the transition from S3 to Azure Storage a little more difficult but I didn't want to add another layer of complexity to my app (Azure Data Lake).
Azure Data Lake Storage (ADLS) Gen 2 has built in support for ACLs at the files and directories level. ADLS Gen 2 is built on Blob Storage. You can easily manage the ACLs with many tools/languages such as Storage Explorer, PowerShell or Python.
The problem is that I cannot find a way to set ACL per file in Azure
Storage, I see I can set ACL in the container, but no in the Blob.
Is there a way to do this, or is not possible in Azure Storage?
The answer to this question is no. You can't set the ACL at the blob container level only by setting it to any of the following values - Private, Blob or Container (Full). All the blobs in that container will follow the same ACL.
Also, RBAC access is again applied at the blob container level and not at the blob level.
I'm not sure if this is exactly what you are looking for.
We can set the ACLs at individual folder/files level in ADLS2. There is a manage access access option in storage explorer and you can set the permissions from there. This is documented here.
I have create more than 3 storage account and 3 VM and 3 Clusters.
Storage Accounts:
Storage Account 1
Storage Account 2
Storage Account 3
I want to know Storage Account 1 is associated with how many VM and Clusters. How can I find it via Azure Portal ?
A storage account isn't an "owned" or "dedicated" resource. That is, even if you use a storage account for a given app or service, there's no tight coupling between the two. Any service / app that has your account credentials (or a SAS link to a specific container/queue/table within your storage account) will be able to use that storage account.
However, if you look at the settings for a given app or service (in your case, your VM or HDInsight), you can see which storage accounts it's using, with a bit of digging. For example, your VM might have both OS and Data disks, with each disk using potentially a different storage account - you'd need to enumerate the OS+attached disks to see which storage accounts are in use for each.
Further, if you create all resources at once (again, imagine creating a new VM with new storage), all of your resources will be bundled together within the same Resource Group.
You can via the new Azure portal to find the Azure Storage Account, in the storage account, you will find the Container. The vhds container used for Azure VM by default, select the vhds, you will find the VMs' VHD files there. About the HDInsight, the default Container name is the HDInsight name, so we can find the result manually.
When working with a VHD hosted within an Azure Storage account, are there any operations one can perform to access the Storage account directly?
I.e. I create a VM and store it's VHD in a blob in account A, are there any local/efficient ways to work with data in account A from the VM?
See if Azure Storage Files service will work for you. You may attach your storage as a file share and communicate with that directly using traditional APIs.
Apart of that, you may use cross-platform Azure Storage Explorer for communicating with other Storage subservices like Blobs.
