第一从头部署es部署机器报错
排查后是因为 

org.elasticsearch.client导致,需排包+指定对应的包版本立即解决,希望能够帮助到别人

原POM

    <dependency>
                <groupId>org.elasticsearch</groupId>
                <artifactId>elasticsearch</artifactId>
                <version>7.10.2</version>
            </dependency>
            <dependency>
                <groupId>org.elasticsearch.client</groupId>
                <artifactId>elasticsearch-rest-high-level-client</artifactId>
                <version>7.10.2</version>
            
           </dependency>

解决后的POM

    <dependency>
                <groupId>org.elasticsearch</groupId>
                <artifactId>elasticsearch</artifactId>
                <version>7.10.2</version>
            </dependency>
            <dependency>
                <groupId>org.elasticsearch.client</groupId>
                <artifactId>elasticsearch-rest-client</artifactId>
                <version>7.10.2</version>
            </dependency>
            <dependency>
                <groupId>org.elasticsearch.client</groupId>
                <artifactId>elasticsearch-rest-high-level-client</artifactId>
                <version>7.10.2</version>
                <exclusions>
                    <exclusion>
                        <groupId>org.elasticsearch.client</groupId>
                        <artifactId>elasticsearch-rest-client</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>

排除 elasticsearch-rest-client 并指定版本就可以
