I was able to install Datastax Enterprise 3.0 and add 3 notes successfully when I first did it around April 8th. When I tried to add another new cassandra node recently, I am getting "Install Errored: Unable to dry-run package installation". Close to the bottom of the message window, It stated "dse: Depends: dse-libhadoop-native(= 3.0-1) but it is not going to be installed. Recommends:sun-java6-jre(>=6.24-1~squeeze1) but it is not installable"
Why am I getting the error which I did not get when I did my first installation. I do have java version "1.6.0_43" installed.
