Ivan A. Veselovsky commented on HADOOP-9205: -------------------------------------------- Shortest way to reproduce the issue: Run test org.apache.hadoop.util.TestNativeCodeLoader with -Drequire.test.libhadoop=true and env variable LD_LIBRARY_PATH=.../hadoop-common/hadoop-common-project/hadoop-common/target/native/target/usr/local/lib If you're running on Java 1.6, the test passes. If you're running on Java 1.7, the test fails. If we add parameter -Djava.library.path=.../hadoop-common/hadoop-common-project/hadoop-common/target/native/target/usr/local/lib , the test passes on both 1.6 and 1.7. This is reproducible with Oracle's JDK jdk1.7.0_07, jdk1.7.0_10, but is *not* reproducible with jdk1.7.0_05, so Kihwall's observation regarding 1.7.0_05 is correct. > Java7: path to native libraries should be passed to tests via > -Djava.library.path rather than env.LD_LIBRARY_PATH > ----------------------------------------------------------------------------------------------------------------- > > Key: HADOOP-9205 > URL: https://issues.apache.org/jira/browse/HADOOP-9205 > Project: Hadoop Common > Issue Type: Bug > Affects Versions: 3.0.0, 2.0.3-alpha, 0.23.6 > Reporter: Ivan A. Veselovsky > Assignee: Ivan A. Veselovsky > Attachments: HADOOP-9205.patch > > > Currently the path to native libraries is passed to unit tests via > environment variable LD_LIBRARTY_PATH. This is okay for Java6, but does not > work for Java7, since Java7 ignores this environment variable. > So, to run the tests with native implementation on Java7 one needs to pass > the paths to native libs via -Djava.library.path system property rather than > the LD_LIBRARY_PATH env variable. > The suggested patch fixes the problem via setting the paths to native libs > using both LD_LIBRARY_PATH and -Djava.library.path property. This way the > tests work equally on both Java6 and Java7. -- This message is automatically generated by JIRA.
