> Fix -Xcheck:jni issues in libhdfs, run ctest with -Xcheck:jni enabled
> ---------------------------------------------------------------------

> Key: HDFS-14321
> URL: https://issues.apache.org/jira/browse/HDFS-14321
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs-client, libhdfs, native
> Reporter: Sahil Takiar

>
> The JVM exposes an option called {{-Xcheck:jni}} which runs various checks
> against JNI usage by applications. Further explanation of this JVM option can
> be found in:
> [https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/clopts002.html]
> and
> [https://www.ibm.com/support/knowledgecenter/en/SSYKE2_8.0.0/com.ibm.java.vm.80.doc/docs/jni_debug.html].
> When run with this option, the JVM will print out any warnings or errors it
> encounters with the JNI.
> We should run the libhdfs tests with {{-Xcheck:jni}} (can be added to
> {{LIBHDFS_OPTS}}) and fix any warnings / errors. We should add this option to
> our ctest runs as well to ensure no regressions are introduced to libhdfs.
