[jira] [Created] (HADOOP-12845) Improve Openssl library finding on RedHat system

Sebastien Barrier created HADOOP-12845:
------------------------------------------

             Summary: Improve Openssl library finding on RedHat system
                 Key: HADOOP-12845
                 URL: https://issues.apache.org/jira/browse/HADOOP-12845
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.7.2
            Reporter: Sebastien Barrier
            Priority: Minor


The issue is related to [https://issues.apache.org/jira/browse/HADOOP-11216].

In the BUILDING.txt it's specified "Use -Drequire.openssl to fail the build if libcrypto.so is not found".

On RedHat system (Fedora/Centos/...) the /usr/lib64/libcrypto.so is a link provided by openssl-devel RPM package which is fine on a build/development host,  but devel packages are not supposed to be installed on Production servers (Hadoop Cluster) and the openssl RPM package don't include that link which is a problem.

# hadoop checknative -a
...
openssl: false Cannot load libcrypto.so (libcrypto.so: cannot open shared object file: No such file or directory)!

There's only /usr/lib64/libcrypto.so.10 but no /usr/lib64/libcrypto.so

Also trying to compile with "-Drequire.openssl -Dopenssl.lib=/usr/lib64/libcrypto.so.10" failed.
