java.lang.IllegalStateException: codebase property already set: codebase.elasticsearch-analysis-ik -> file:/usr/share/elasticsearch/plugins/ik/elasticsearch-analysis-ik-7.14.1.jar, cannot set to file:/usr/share/elasticsearch/plugins/ik/elasticsearch-analysis-ik-7.4.2.jar"
安装ik分词器的时候，一直安装不成功，后面发现是安装的时候，是传过去虚拟机那边的，先下了7.14的版本，后面下了7.4.2的版本，然后解压到同一个目录下出现了jar包冲突了。
解决方法：
rm -rf elasticsearch-analysis-ik-7.14.1.jar
移除冲突的jar包
然后重新启动es
docker restart xxx
docker ps -a
最后的结果
docker logs xxx查看日志
测试
