使用 Java 11 启动弹性搜索 5.0.1 时出现 AccessControlException

Question

使用 Java 11 将索引从弹性搜索 5.0.1 存储到 NFS 分区时出现异常。

来自弹性搜索日志的 Stacktrace：

注意：相同的设置适用于 Java8

Answer 1

回答Java版本的问题：

this thread 中的讨论是说版本 6.x 将支持 Java 11。

Here 是当前支持的 Java 版本的概述。版本 6.5.x 支持 Java 11。

但是这个异常更可能是因为 elasic 进程在异常信息中没有对文件系统文件夹的写权限：

access denied ("java.io.FilePermission" "/globalSearchElkData/nodes/0" "write")

请检查文件夹/globalSearchElkData/nodes/0

的权限
