无法调试jvm?

[lialzm]

使用ps aux可以看到相关程序,但是使用 jstack 提示

Unable to open socket file: target process not responding or HotSpot VM not loaded

[zeromake]

应该是文件路径挂在了其它地方导致jstack去调取文件按原来路径，导致了无法打开调试的socket文件。

我连java都没法执行，这个能想办法解决吗？

[zeromake]

@xiongjy2104 可以尝试把原容器的 PATH 继承过来，你用的镜像是哪个呢？我试试效果，如果可以我加个参数来继承环境变量。

我用的s1mplecc/spark-hadoop:3，或者我把compose文件放上来你看看。我自己尝试添加JAVA_HOME映射也不行。诉求一个是java命令，另一个是里面的spark-shell命令能运行。
