Description

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.

1. 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.
