Summary: Ambari Automated Kerberization
Key: AMBARI-7204
URL: https://issues.apache.org/jira/browse/AMBARI-7204
Project: Ambari
Issue Type: Epic
Components: ambari-server, security, stacks
Affects Versions: 2.0.0
Environment: Kerberos
Reporter: Robert Levas
*Problem*
Manually installing and setting up Kerberos for a secure Hadoop cluster is
error prone, largely manual and a potential source of configuration problems.
It requires many steps where configuration files and credentials may need to be
distributed across many nodes. Because of this the process is time consuming
and lead to a high probability of user error.
The problem is exacerbated when the cluster is modified by adding or removing
nodes and services.
*Solution*
Use Ambari to secure the cluster using Kerberos. By automating the process of
setting up Kerberos, the repetitive tasks of distributing configuration details
and credentials can be done in parallel to the nodes within the cluster. This
also negates most user-related errors due to the lack of interaction a user has
with the process.
