Hi @Sandeep Nemuri, Below is the script I am working on and its working fine when I am running the same on ambari host but it's started giving an error when the same running on its nodes because that time localhost gets changed. Can you please suggest me what to use to get the ambari host value when I will erun the same script on different nodes? #!/bin/bash AMBARI_HOST=localhost echo "AMBARI_HOST: "$AMBARI_HOST HOST_NAME=$(hostname --fqdn) echo "HOST_NAME: "HOST_NAME AMBARI_PASSWORD=xxxxxxxxxxxx #detect name of cluster # CLUSTER_OUTPUT=$(curl -u admin:$AMBARI_PASSWORD -i -H 'X-Requested-By: ambari' http://$AMBARI_HOST:8080/api/v1/clusters) export CLUSTER=$(echo $CLUSTER_OUTPUT | sed -n 's/.*"cluster_name" : "\([^\"]*\)".*/\1/p') echo $CLUSTER curl -iv -u admin:$AMBARI_PASSWORD -H "X-Requested-By: ambari" -X PUT -d '{"RequestInfo":{"context":"Stopping All Host Components","operation_level": {"level":"HOST","cluster_name":"autoshutdown", "host_names":"$HOST_NAME"},"query":"HostRoles/component_name/*"}, "Body": {"HostRoles": {"state":"INSTALLED"}}}' http://$AMBARI_HOST:8080/api/v1/clusters/autoshutdown/hosts/$HOST_NAME/host_components
