In application-dev.yml file I have entered the database credentials :
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://localhost:3306/bsadhana?useUnicode=true&characterEncoding=utf8&useSSL=false&useLegacyDatetimeCode=false&serverTimezone=UTC&createDatabaseIfNotExist=true
username: root
password: rxxxx!

Even the jhipster related tables were created in my database. But when I am trying to create a new user it is throwing the above-reported error. is there anywhere else I need to enter these credentials?
The error says your app cannot connect to your Elasticsearch instance, you should make sure you started it with following command as explained in the doc:
docker-compose -f src/main/docker/elasticsearch.yml up

Please help to fix the issue.. Thanks in advance
Someone changed the configs of email server in the machine itself.. So when i wrote the configuration in Jenkins it was attempting to overwrite the machine configuration and eventually timed out so i removed the config and it worked fine..
I've this problem with supervisor:
DRPCSpout [ERROR] Failed to fetch DRPC result from DRPC server
org.apache.thrift7.transport.TTransportException: java.net.ConnectException:
Connection refused
