Elasticsearch启动报错

1、ES启动报错“The Security Manager is deprecated and will be removed in a future release”，查看jdk版本。

2、ES支持的jdk版本及问题讨论。

【Support Matrix】https://www.elastic.co/support/matrix#matrix_jvm
【The Security Manager is deprecated exception (ES wont start) #85665】https://github.com/elastic/elasticsearch/issues/85665

3、jdk更换，重启。
