##   In some of the installs, I recieved the following error in the ambari-agent log. 
##   by monitoring:  tail -F /var/log/ambari-agent/ambari-agent.log
##   
##   NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions.
##   
##   
##   the sulutions that worked best for me were changes to:
##   1. /etc/ambari-agent/conf/ambari-agent.ini
##   2. /etc/python/cert-verification.cfg 
##   
sed -i "s/ssl_verify_cert=0/ssl_verify_cert=0\nforce_https_protocol=PROTOCOL_TLSv1_2/" /etc/ambari-agent/conf/ambari-agent.ini
sed -i.ORIG 's/verify=platform_default/verify=disable/' /etc/python/cert-verification.cfg
##   
##   now restart the server & agent:
ambari-server restart
ambari-agent restart
##   
##   If need to restart the installation - this may help - but not tested explicitly:
blueprint_name=${1:-hdp-setup-bluprint}
cluster_name=${2:-host_group_1}
dest_hostname=$(hostname -f)
#   
curl -H "X-Requested-By: ambari" -X POST -u admin:admin http://${dest_hostname}:8080/api/v1/blueprints/${blueprint_name} -d @cluster_configuration.json
curl -H "X-Requested-By: ambari" -X POST -u admin:admin http://${dest_hostname}:8080/api/v1/clusters/${cluster_name} -d @hostmapping.json
# but may need first to delete the blueprints.
curl -H "X-Requested-By: ambari" -X DELETE -u admin:admin http://${dest_hostname}:8080/api/v1/blueprints/${blueprint_name} 
curl -H "X-Requested-By: ambari" -X DELETE -u admin:admin http://${dest_hostname}:8080/api/v1/clusters/${cluster_name}
