Subject [jira] [Created] (HADOOP-8806) libhadoop.so: search java.library.path when calling dlopen
Date Thu, 13 Sep 2012 22:28:07 GMT
Colin Patrick McCabe created HADOOP-8806:
--------------------------------------------

             Summary: libhadoop.so: search java.library.path when calling dlopen
                 Key: HADOOP-8806
                 URL: https://issues.apache.org/jira/browse/HADOOP-8806
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Colin Patrick McCabe
            Priority: Minor


libhadoop calls {{dlopen}} to load {{libsnappy.so}} and {{libz.so}}.  These libraries can
be bundled in the {{$HADOOP_ROOT/lib/native}} directory.  For example, the {{-Dbundle.snappy}}
build option copies {{libsnappy.so}} to this directory.  However, snappy can't be loaded from
this directory unless {{LD_LIBRARY_PATH}} is set to include this directory.

Should we also search {{java.library.path}} when loading these libraries?
