If you are trying to read append blobs using Spark and getting something like
java.io.IOException: com.microsoft.azure.storage.StorageException: Incorrect Blob type, please use the correct Blob type to access a blob on the server. Expected BLOCK_BLOB, actual APPEND_BLOB.
just know there’s no workaround or plans to support append blobs. You’re out of luck. Go away and search for alternative ways to access append blobs, like with native blob SDK.
