遇到的问题

uncaught exception in thread [main]

org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: Cannot replace existing handler for [/_sql] for method: POST

原因：elasticsearch-sql与自带的x-pack-sql模块冲突，vi /opt/elasticsearch/config/elasticsearch.yml 修改

xpack.sql.enabled: false重启ES
