Subject [jira] Created: (HADOOP-6069) Remove explicit dynamic loading of libz in native code

Remove explicit dynamic loading of libz in native code

                 Key: HADOOP-6069
                 URL: https://issues.apache.org/jira/browse/HADOOP-6069
             Project: Hadoop Core
          Issue Type: Improvement
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon

The native zlib code currently uses dlopen/dlsym to dynamically load libz. This used to make
sense when there was an lzo option (so you could load libhadoop for lzo purposes without requiring
libz as well). Now that libhadoop only has zlib as an option, it makes sense to just add it
as an ld flag and let it be automatically loaded as a shlib dependency. I also doubt that
there are any distros where libz isn't required by the base system.
