User access requirements

The Linux user that performs the installation must be the one that will run all BDD processes after the installation and can't be the root user. The following must be configured for this user:

Password-less sudo-to-root enabled on all nodes in the cluster, including Hadoop nodes.
Bash set as the default shell on all nodes in the cluster, including Hadoop nodes.
Permission to create the directory in which BDD and the WebLogic Server will be installed on all nodes in the cluster, including Hadoop nodes. (This directory is defined by the ORACLE_HOME property in the BDD configuration file.)
Passwordless SSH enabled so they can log into all other nodes in the cluster (including Hadoop nodes) from the install machine (instructions are available in the following topic).
