Description

I built Hadoop from fs-encryption branch and deployed Hadoop (without enabling any security confs) on a Centos 6.4 VM with an old version of openssl.

[root@schu-enc hadoop-common]# rpm -qa | grep openssl
openssl-1.0.0-27.el6_4.2.x86_64
openssl-devel-1.0.0-27.el6_4.2.x86_64

When I try to do a simple "hadoop fs -ls", I get

[hdfs@schu-enc hadoop-common]$ hadoop fs -ls

It would be an improvment to clean up/shorten this error log.

hadoop checknative shows the error as well
