Hadoop cluster

Apache Hadoop version 2.0.0 or higher is installed within a corporate infrastructure, either on-premise or within the cloud (e.g. Microsoft Azure, Amazon’s AWS or Cloudera CDH5).
1. The recommended Hadoop version is 2.4.0 or higher where major supportability improvements and bug fixes were applied to WebHDFS and HttpFS.
Enable/Install the HttpFS or WebHDFS service on the Hadoop cluster.
1. HttpFS is Datavard’s recommended option. It is more efficient because it does not require redirection to be handled by the client. It is also easier to install and configure within a corporate infrastructure because it acts as gateway (single point of access); therefore, it can be placed behind a firewall.
Enable/Install the Oozie service on the Hadoop cluster.
1. The recommended Oozie version is 4.0.0 or higher where major supportability improvements and bug fixes were applied. For extended job log information Oozie version 4.2.0 or higher is required.
