Troubleshoot SQL Server Big Data Cluster Active Directory integration
Applies to: 
SQL Server 2019 (15.x)
This article explains how to troubleshoot deployment of a SQL Server Big Data Cluster in Active Directory mode.
Important
The Microsoft SQL Server 2019 Big Data Clusters add-on will be retired. Support for SQL Server 2019 Big Data Clusters will end on February 28, 2025. All existing users of SQL Server 2019 with Software Assurance will be fully supported on the platform and the software will continue to be maintained through SQL Server cumulative updates until that time. For more information, see the announcement blog post and Big data options on the Microsoft SQL Server platform.
Symptom
You started deploying SQL Server Big Data Clusters with Active Directory mode. The deployment is stuck and not moving forward.
The following example shows the deployment results in a bash shell.

NOTE: Cluster creation can take a significant amount of time depending on
configuration, network speed, and the number of nodes in the cluster.

Check the current deployed pods.
kubectl get pods -n mssql-cluster
The following list shows only pods that belong to the controller have been deployed. No compute, data or storage pool pods are being created.

Check logs
To identify why deployment quit without creating compute, data, or storage pods, check the following logs:
Check
controller.log(<folderOfDebugCopyLog>\debuglogs-mssql-cluster-20200219-093941\mssql-cluster\control-<suffix>\controller\controller\<date>\controller.log). Look for the following entry:WARN | StatefulSet master is not ready with 0 ready pods and 3 unready podsCheck

WARNING | Failed to create sql login for domain user [<domain>.<top-level-domain>\<domain-group>] WARNING | Retrying.
Cause
In the example above, the deployment fails to create a login for the domain user because the domain group is scoped as domain local. Use global or universal scoped groups. To learn about Active Directory group scope requirements, see Deploy SQL Server Big Data Clusters in Active Directory mode.
Verify
Check the scope of the domain group (<domain-group>). Use get-adgroup.
If the <domain-group> group scope is domain local (DomainLocal) deployment fails.
The following PowerShell script checks the scope of two Active Directory groups named bdcadmins and bdcusers. Replace the names with the names for your groups.
#Administrators and users Active Directory groups
$Cluster_admins_group='bdcadmins'
$Cluster_users_group='bdcusers'
#Performing Active Directory Group Checks...
#Active Directory admin group Check
$ClusterAdminGroupScope_Result = New-Object System.Collections.ArrayList
try {
$GroupScope = Get-ADgroup -Identity $Cluster_admins_group | Select-Object -ExpandProperty GroupScope
if ($GroupScope -eq 'DomainLocal') {
[void]$ClusterAdminGroupScope_Result.Add("Misconfiguration - $Cluster_admins_group Group scope is $GroupScope, this scope is not supported, Please change group scope to either Global or Univesal")
}
else {
[void]$ClusterAdminGroupScope_Result.Add("OK - $Cluster_admins_group Group scope is $GroupScope")
}
}
catch {
[void]$ClusterAdminGroupScope_Result.Add("Error - " + $_.exception.message)
}
#Ad users group check
$ClusterUsersGroupScope_Result = New-Object System.Collections.ArrayList
$GroupScope = ''
try {
$GroupScope = Get-ADgroup -Identity $Cluster_users_group | Select-Object -ExpandProperty GroupScope
if ($GroupScope -eq 'DomainLocal') {
[void]$ClusterUsersGroupScope_Result.Add("Misconfiguration - $Cluster_users_group Group scope is $GroupScope, this scope is not supported, Please change group scope to either Global or Univesal")
}
else
{ [void]$ClusterUsersGroupScope_Result.Add("OK - $Cluster_users_group Group scope is $GroupScope") }
}
catch {
[void]$ClusterUsersGroupScope_Result.Add("Error - " + $_.exception.message)
}
#Display the results
$ClusterUsersGroupScope_Result
Resolution
To resolve the problem, create the Active Directory groups with either universal or global scope and run the deployment again.
