Install and Configuration Changes
Integration with Ambari cluster manager ambari interface/integration. The Ambari integration provides support for Hortonworks Hadoop distributions, while the command-line Trafodion Installer supports Cloudera and Hortonworks Hadoop distributions, and for select vanilla Hadoop installations.
Trafodion Installer Evolution The command-line installer has been replaced for the 2.1.0 release. Written in python, it replaces the legacy bash-script installer. The bash command-line installer is deprecated as of 2.1.0, but is still provided, just in case you experience any problems with the new installer. If so, please report those problems to the project team, since the legacy installer will soon be obsoleted.
