My cluster used to had 2 node,
this node as : master

I reconfigure elasticsearch.yml on master to make it as default ,
but when I try to rune the previously master node it returning
{"statusCode":503,"error":"Service Unavailable","message":"License is not available."}

I've tried some solution here solutions from github, https://discuss.elastic.co/t/elasticsearch-wont-start-after-7-9-1-to-7-9-2-upgrade/249878/2
8-13:-XX:+UseConcMarkSweepGC
8-13:-XX:CMSInitiatingOccupancyFraction=75
8-13:-XX:+UseCMSInitiatingOccupancyOnly
not working,
-XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=75
-XX:+UseCMSInitiatingOccupancyOnly
not working
#-XX:+UseConcMarkSweepGC
#-XX:CMSInitiatingOccupancyFraction=75
#-XX:+UseCMSInitiatingOccupancyOnly
not working either
any suggestion will be appreciated
