Thank you Ann
it was log4j file in elasticserach/lib folder, we renamed that file, when the server restarted, elastic search was not coming up without log4j.
we restored the file, then it started working.
upgraded Sonarqube to 9.9.4, it looks good , up and running.
I see this warning msg in startup, do we need to fix this warning?
