    +[[introduction]]
    += Introduction
    +
    +Trafodion is a Hadoop add-on service that provides transactional SQL on top of HBase.
Typically, you
    +use Trafodion as the database for applications that require Online Transaction Processing
(OLTP),
    +Operational Data Store (ODS), and/or strong reporting capabilities. You access Trafodion
using
    +standard JDBC and ODBC APIs.
    +
    +You may choose whether to add Trafodion to an existing Hadoop environment or to create
a standalone
    +Hadoop environment specifically for Hadoop.
    +
    +This guide assumes that a Hadoop environment exists upon which your provisioning Trafodion.
Refer to
    +<<requirements-hadoop-software,Hadoop Software>> for information about what
Hadoop software is required
    +Trafodion.
    +
    +[[introduction-security-considerations]]
    +== Security Considerations
    +
    +The following users need be considered for Trafodion:
    +
    +* *Provisioning User*: A Linux-level user that performs the Trafodion provisioning tasks.
This user ID
    +requires `sudo` access and passwordless ssh among the nodes where Trafodion is installed.
In addition,
    +this user ID requires access to Hadoop distribution, HDFS, and HBase administrative users
to change
    +respective environment's configuration settings per Trafodion requirements. Refer to
    +<<requirements-trafodion-provisioning-user,Trafodion Provisioning User>>
for more information
    +about the requirements and usage associated with this user ID.
    +
    +* *Runtime User*: A linux-level user under which the Trafodion software runs. This user
ID must be registered
    +as a user in the Hadoop Distributed File System (HDFS) to store and  access objects in
HDFS, HBase, and Hive.
    +In addition, this  user ID requires passwordless access among the nodes where Trafodion
is installed.
    +Refer to <<requirements-trafodion-runtime-user,Trafodion Runtime User>> for
more information about this user ID.
    +
    +* *Trafodion Database Users*: Trafodion users are managed by the Trafodion security features
(grant, revoke, etc.),
    +which can be integrated with LDAP if so desired. These users are referred to as *database
users* and
    +do not have direct access to the operating system. Refer to 
    +http://trafodion.apache.org/docs/sql_reference/index.html#register_user_statement[Register
User],
    +http://trafodion.apache.org/docs/sql_reference/index.html#grant_statement[Grant], and
other SQL statements
    +in the http://trafodion.apache.org/docs/sql_reference/index.html[Trafodion SQL Reference
Manual] for
    +more information about managing Trafodion Database Users.
    + +
    + +
    +Optionally, you can enable Trafodion Security. If you do not enable security in Trafodion,
then a client interface
    +to Trafodion may request a user name and password, but Trafodion ignores the user name
and password entered in the
    +client interface, and the session runs as the database *root* user, `DB__ROOT`, without
restrictions. If you want
    +to restrict users, restrict access to certain users only, or restrict access to an object
or operation, then you must
    +enable security, which enforces authentication and authorization. Refer to
    +<<enable-security,Enable Security>> for more information about this option.
    +

    +Trafodion ships with a set of scripts (the Trafodion Installer) that takes care of many
of the installation and upgrade
