解决方案)

问题背景

在安装elasticsearch的分词器ik的时候报错：
容器里面查询

elasticsearch-plugin list

elasticsearch-analysis-ik-7.4.2.zip
Exception in thread "main" java.nio.file.FileSystemException: /usr/share/elasticsearch/plugins/elasticsearch-analysis-ik-7.4.2.zip/plugin-descriptor.properties: Not a directory

解决方案

从报错看出elasticsearch-analysis-ik-7.4.2.zip： Not a directory，这个安装包不是一个文件夹，elasticsearch的plugins下面只能放着的是一个个文件夹插件，所以把elasticsearch-analysis-ik-7.4.2.zip删除就可以了

rm -rf elasticsearch-analysis-ik-7.4.2.zip

总结

多看报错信息
