Nalini Ganapati created HDFS-13585: -------------------------------------- Summary: libhdfs SIGSEGV during shutdown of Java application. Key: HDFS-13585 URL: https://issues.apache.org/jira/browse/HDFS-13585 Project: Hadoop HDFS Issue Type: Bug Components: native Affects Versions: 2.7.5 Environment: Centos 7 Reporter: Nalini Ganapati
We are using libhdfs for hdfs support from our native library. This has been working mostly fine with Java/Spark applications, but some of them throw a SIGSEGV in hdfsThreadDestructor(). We tried to dynamically load and unload libhdfs.so using dlopen/dlclose but to no avail and we still see the seg fault. Is this a known issue? Looks like thread local storage is involved, are there workarounds?
