> Add container balancer recommend CLI command to suggest config values for
> slow/medium/fast profiles

> Key: HDDS-16181
> URL: https://issues.apache.org/jira/browse/HDDS-16181
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Sreeja Chintalapati
> Assignee: Sravani Revuri
> Priority: Major
>
> Add ozone admin containerbalancer recommend command
> The command should:
> # Fetch live datanode usage from SCM (via the existing getDatanodeUsageInfo
> RPC)
> # Read local Ozone configuration for global defaults (threshold, timeouts,
> move limits etc.)
> # Analyze the cluster using existing {{ContainerBalancerClusterAnalyzer}} /
> {{ContainerBalancerClusterSnapshot}} (HDDS-16173)
> # For each profile (SLOW, MEDIUM, FAST), produce:
> ** Recommended configuration parameters with a short rationale
> ** Time/iteration estimates by reusing
> {{ContainerBalancerAdvisor.estimateDryRun()}} (HDDS-16179)
> ** Each recommended values should be validated first.
> No --profile, config overrides, or interactive mode on this command
> If the user wants custom inputs or refined estimates, they use dry-run
> instead.
> But the command should allow the user to provide include/exclude datanodes
> and threshold values.
