Library Support for AES-NI optimization
You will need a version of the libcrypto.so
library that supports
hardware acceleration, such as OpenSSL 1.0.1e. (Many OS versions have an older
version of the library that does not support AES-NI.)
A version of the libcrypto.so
library with AES-NI support must be
installed on HDFS cluster nodes and MapReduce client hosts -- that is, any
host from which you issue HDFS or MapReduce requests. The following
instructions describe how to install and configure the
libcrypto.so
library.
RHEL/CentOS 6.5 or later
On HDP cluster nodes, the installed version of libcrypto.so
supports
AES-NI, but you will need to make sure that the symbolic link exists:
$ sudo ln -s /usr/lib64/libcrypto.so.1.0.1e
/usr/lib64/libcrypto.so
On MapReduce client hosts, install the openssl-devel
package:
$ sudo yum install openssl-devel
