# Add cluster configuration
python ~/.claude/skills/ambari-api/scripts/ambari_api.py config --add \
  --name prod \
  --url https://ambari.example.com:8080 \
  --username admin \
  --password admin

# List clusters
python ~/.claude/skills/ambari-api/scripts/ambari_api.py clusters --config prod

Core Operations

Service Management

bash

# List services in a cluster
python ambari_api.py services --config prod --cluster mycluster

# Start/Stop/Restart a service
python ambari_api.py services --config prod --cluster mycluster --service HDFS --action START
python ambari_api.py services --config prod --cluster mycluster --service YARN --action STOP
python ambari_api.py services --config prod --cluster mycluster --service HIVE --action RESTART

Component Management (Host-Specific)

bash

# List components on a host
python ambari_api.py components --config prod --cluster mycluster --host node01

# Start/Stop specific component on a host
python ambari_api.py components --config prod --cluster mycluster --host node01 \
  --service HDFS --component DATANODE --action START

python ambari_api.py components --config prod --cluster mycluster --host node01 \
  --service HDFS --component DATANODE --action STOP

Host and Status Operations

bash

# List all hosts
python ambari_api.py hosts --config prod --cluster mycluster

# Get service status
python ambari_api.py status --config prod --cluster mycluster --service HDFS

Configuration Management

bash

# List configured clusters
python ambari_api.py config --list

# Remove a cluster configuration
python ambari_api.py config --remove --name prod
