You can make use fo Ambari APIs to do the same and run the following kind of API calls using curl using Cron Job at the mentioned times.

Stop All Services of an ambari managed cluster

curl -u admin:admin  -H 'X-Requested-By:ambari' -X PUT     -d '{"RequestInfo":{"context":"_PARSE_.STOP.ALL_SERVICES","operation_level":{"level":"CLUSTER","cluster_name":"BlueprintCluster"}},"Body":{"ServiceInfo":{"state":"INSTALLED"}}}' http://blueprint.example.com:8080/api/v1/clusters/BlueprintCluster/services?

.

Start All Services of an ambari managed cluster

curl -u admin:admin  -H 'X-Requested-By:ambari' -X PUT     -d '{"RequestInfo":{"context":"_PARSE_.START.ALL_SERVICES","operation_level":{"level":"CLUSTER","cluster_name":"BlueprintCluster"}},"Body":{"ServiceInfo":{"state":"STARTED"}}}' http://blueprint.example.com:8080/api/v1/clusters/BlueprintCluster/services?

Here following are the values that you will have to change:
BlueprintCluster: Replace it with your Cluster Name

blueprint.example.com: Replace it with your Ambari Server Hostname

1. Open a terminal and run the following command to open the crontab editor (it's like "vi" editor)

# crontab -e

2. Now add the following entries inside it: (here 30 17 means 5:30 PM) and similarly (30 06 means 6:30 AM)

30 17 * * * curl -u admin:admin  -H 'X-Requested-By:ambari' -X PUT     -d '{"RequestInfo":{"context":"_PARSE_.STOP.ALL_SERVICES","operation_level":{"level":"CLUSTER","cluster_name":"BlueprintCluster"}},"Body":{"ServiceInfo":{"state":"INSTALLED"}}}' http://blueprint.example.com:8080/api/v1/clusters/BlueprintCluster/services?

30 06 * * * curl -u admin:admin  -H 'X-Requested-By:ambari' -X PUT     -d '{"RequestInfo":{"context":"_PARSE_.START.ALL_SERVICES","operation_level":{"level":"CLUSTER","cluster_name":"BlueprintCluster"}},"Body":{"ServiceInfo":{"state":"STARTED"}}}' http://blueprint.example.com:8080/api/v1/clusters/BlueprintCluster/services?
