Apache Spark Executor JVM在C ++库中崩溃后，我无法找到在Executor JVM输出日志中指定的hs_err_pid.log文件。这是Executor输出日志的示例：
# A fatal error has been detected by the Java Runtime Environment:

但是，当我使用SSH定位目标工作机以定位hs_err_pid28580.log时，找不到该文件的任何痕迹。我尝试过：
vglazkov@reindex-cluster-vg-w-0:~$ sudo find / -name hs_err_pid28580.log
vglazkov@reindex-cluster-vg-w-0:~$
vglazkov@reindex-cluster-vg-w-0:~$ sudo ls -la /hadoop/yarn/nm-local-dir/usercache/root/appcache/
total 12
drwx--x--- 3 yarn yarn 4096 Jun 4 10:46 .

drwx--x--- 3 yarn yarn 4096 Jun 4 10:48 application_1557935076075_0097
但是在最后一种情况下，名为application_1557935076075_0097的目录与我的applicationId application_1559573462307_0002不匹配，并且不包含任何hs_err_pid.log文件
