JDK问题

jdk版本对应

warning: ignoring JAVA_HOME=E:\dev\jdk\jdk17\jdk-17.0.10; using bundled JDK

Exception in thread "main" java.lang.RuntimeException: starting java failed with [1]

output:

#

# There is insufficient memory for the Java Runtime Environment to continue.

# Native memory allocation (mmap) failed to map 8506048512 bytes for G1 virtual space

# An error report file with more information is saved as:

# logs/hs_err_pid18980.log

error:

度娘很多次，搜索warning: ignoring JAVA_HOME=E:\dev\jdk\jdk1.8; using bundled JDK

大多说的是JDK版本不一致，因此我又去下载了很多高版本的JDK，发现结果是一样的

warning: ignoring JAVA_HOME=E:\dev\jdk\jdk17; using bundled JDK

后面在elasticsearch-env.bat文件中发现他使用的是ES_JAVA_HOME，然后在环境变量中添加了ES_JAVA_HOME对应jdk17

elasticsearch-rest-high-level-client:jar:8.12.2 was not found,elasticsearch,大数据,搜索引擎

内存问题

当然没有这么顺利一下子就弄好了，改完这个之后，发现还是报错
