HBase Snapshotting Failed because of Failure to aquire SAS Token

[#1]

Hello,

<in a Public Cloud Environment in the Operational Database with Azure: Snapshots were failing.
The HBase-Service Command Tab showes that it occurs while copying a snapshot to another directory because it could not acquire a SAS token. (*)
Usually those errors are related to missing rights on Managed Identities. 
- But we double-checked all Azure Managed Identity IAMs and RBACs.
Sometimes the SAS-Token Failure is related to Kerberos which is disabled./>

What could have gone wrong? 

(*):
Client.RangerRESTClient: ===>> RangerRESTClient.init() : Since mKeyStoreType is NULL, setting System default.

[mKeyStoreType=jks] Exception in thread "main" Failed to acquire a SAS token for get-acl on / due to org.apache.hadoop.security.AccessControlException: Permission denied. at org.apache.hadoop.fs.azurebfs.services.AbfsClient.appendSASTokenToQuery(AbfsClient.java:1233)
