   In Installing DataStax Enterprise RHEL or CentOS Packages

   Step 4 of The installation instructions state

   4. (Optional) Install JNA:

   
# yum install jna


   Unfortunately jna is not in the repo:

   
# cat /etc/yum.repos.d/datastax.repo
[datastax]
name= DataStax Repo for Apache Cassandra
baseurl=http://<username>:<password>@rpm.datastax.com/enterprise # username and password removed
enabled=1
gpgcheck=0

   # yum install jna
   Setting up Install Process
   No package jna available.
   Nothing to do

   #yum list available *jna*
Error: No matching Packages to list


   It would also be nice if all the other dependencies for dse-full were in the repo (i.e. python2.6 and its dependancies)

   thanks,

   Rob

   These should be available in the EPEL repo mentioned in step 1 here: http://www.datastax.com/docs/datastax_enterprise2.0/install_dse_packages#installing-datastax-enterprise-rhel-or-centos-packages

   I did not run that command because it stated (CentOS 5.x only) and I am running Redhat. Does this need to be run on redhat also?

   The best way is to install from repo package, but I don't know if the EPEL repo works also on RHEL. On CentOS 5.8 I had not problems with it.

   However, if you fail to install from the repo, it is always possible to download the jna.jar 3.4 manually e.g. from here: https://github.com/twall/jna and put it either into /usr/share/java or /usr/share/dse/cassandra/lib.

   Notes:
   1. JNA is not a mandatory dependency to make DSE run. It only allows for improved performance.
   2. If JNA is installed properly, you should see "JNA mlockall successfull" message close to the beginning of the system.log.

   rdinoff, that step is needed for RHEL 5.x as well. I'll be sure to get our docs updated. Thanks
