When we compile Openssl 1.0.0(x) or 1.0.1(x) using default options, there will be libcrypto.so.1.0.0 in output lib dir, so we expect this version suffix in cmake build file
If we don't bundle the crypto shared library in Hadoop distribution, then Hadoop will try to find crypto library in system path when running.
But in real linux distribution, there may be no libcrypto.so.1.0.0 or libcrypto.so even the system embedded openssl is 1.0.1(x). Then we need to make symbolic link.
This JIRA is to improve the Openssl library finding.
