The error is in the log, you need to check your configuration file. > Jun 04 08:57:00 ip-172-31-82-55 systemd-entrypoint[1671]: Caused by: com.fasterxml.jackson.core.JsonParseException: **Duplicate field**'cluster.initial\_master\_nodes' It says that you have a duplicate line for `cluster.initial_master_nodes`. ---
