Cloudera management cloud console

Question

Hi all,I'm having trouble during the provisioning of an environment via cloudera manager cloud console.I followed the quick start, https://docs.cloudera.com/management-console/cloud/azure-quickstart/topics/mc-azure-quickstart.html and the guide on the repository https://github.com/cpv0310/cdp-azure-tools, but the problem remains the same:hdfs can't write to storage abfs: // data @ xxx I tried to create the managed identity both through the template and through the script provided, but I have not had any changes. The only different thing is that in the guide, step 6, it says to assign both assumer identity and data identity, but in the form I only have the possibility to assign the assumer identity. Same thing when I go to assign the identity logger: I only have one slot and I can't assign the identity ranger.  In the logs I see that the creation of the data lake stops trying to create the first folder on HDFS (abfs) and the error is on the "slave" node which through knox has a 403 forbidden. As soon as possible I attach the logs.  Thanks in advance

Ok, I solved it using the cdp cli.

The problem was that from web ui of Cloudera Management Console it is not possible to insert the identity for ranger, while from cli it is possible.
Below are the scripts for creating the data lake environment:

cdp environments create-azure-environment \
--environment-name <ENV_NAME> \
--credential-name <CREDENTIAL_NAME> \
--region "AZURE_REGIONE_NAME" \
--security-access cidr=0.0.0.0/0 \
--no-enable-tunnel \
--public-key "ssh-rsa ..." \
--log-storage storageLocationBase=abfs://logs@<STORAGE_ACCOUNT_NAME>.dfs.core.windows.net,managedIdentity=/subscriptions/xxx/resourcegroups/<RG_NAME>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<ENV_NAME>-LoggerIdentity \
--use-public-ip \
--existing-network-params networkId=<ENV_NAME>-Vnet,resourceGroupName=<ENV_NAME>,subnetIds=CDP \
--free-ipa instanceCountByGroup=1 

cdp environments set-id-broker-mappings \
--environment-name <ENV_NAME> \
--data-access-role /subscriptions/xxx/resourceGroups/<RG_NAME>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<ENV_NAME>-DataAccessIdentity \
--ranger-audit-role /subscriptions/xxx/resourceGroups/<RG_NAME>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<ENV_NAME>-RangerIdentity \
--set-empty-mappings 

cdp datalake create-azure-datalake \
--datalake-name <ENV_NAME> \
--environment-name <ENV_NAME> \
--cloud-provider-configuration managedIdentity=/subscriptions/xxx/resourcegroups/<RG_NAME>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<ENV_NAME>-AssumerIdentity,storageLocation=abfs://data@<STORAGE_ACCOUNT_NAME>.dfs.core.windows.net \
--scale LIGHT_DUTY \
--runtime 7.2.7

Here instead the dockerfile for those wishing to have the cdp-cli in cointainer:

FROM python

RUN apt update \
    && apt upgrade -y \
    && apt install -y \
    groff \
    less

RUN git clone https://github.com/cloudera/cdpcli.git \
    && cd cdpcli \
    && pip install .

This is the error log from the "slave" node when knox is started. I have no idea why it is used knox to access to abfs, but it is consistent with the symptoms: 2021-03-08 16:15:28,657 ERROR idbroker.azure (KnoxMSICredentials.java:httpPatchRequest(416)) - Request to attach identities to VM failed with response code 400, message: {"error":{"code":"FailedIdentityOperation","message":"Identity operation for resource '/subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.Compute/virtualMachines/xxx' failed with error 'Failed to perform resource identity operation.
