---------------------------------
"Recompile libhdfs in a new env then this problem never happens again."
hi, [~Kotomi] , what changed in your new env, we encount same problem now
> libhdfs SIGSEGV during shutdown of Java
> ---------------------------------------
>
> Key: HDFS-14488
> URL: https://issues.apache.org/jira/browse/HDFS-14488
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: native
> Affects Versions: 2.7.3, 3.2.0
> Environment: Centos 7
> gcc (GCC) 8.3.0
> Reporter: Kotomi
> Priority: Critical
>
> For short, it‘s quite similar to
> https://issues.apache.org/jira/browse/HDFS-13585，but backtrace is different.
> We are using libhdfs for hdfs support in our native library, as a plugin,
> _dlopen_ when hdfs path detected and _dlclose_ when application closes.
> Crash happens randomly, during shutdown of Java. GDB shows in function
> hdfsThreadDestructor, JNIEnv v is not NULL but looks like a wild pointer.
> Therefore, it crashes when trying to get JavaVm from its own JNIEnv.
> {code:java}
> 43: ret = (*env)->GetJavaVM(env, &vm);
> {code}
> Any workarounds? Thx.
