Requirements for Guests
|
|
=======================
|
|
|
|
Sahara manages guests of various platforms (for example Ubuntu, Fedora, RHEL,
|
|
and CentOS) with various versions of the Hadoop ecosystem projects installed.
|
|
There are common requirements for all guests, and additional requirements based
|
|
on the plugin that is used for cluster deployment.
|
|
|
|
Common Requirements
|
|
-------------------
|
|
|
|
* The operating system must be Linux
|
|
* cloud-init must be installed
|
|
* ssh-server must be installed
|
|
|
|
+ if a firewall is active it must allow connections on port 22 to enable ssh
|
|
|
|
Vanilla Plugin Requirements
|
|
---------------------------
|
|
|
|
If the Vanilla Plugin is used for cluster deployment the guest is required to
|
|
have
|
|
|
|
* ssh-client installed
|
|
* Java (version >= 6)
|
|
* Apache Hadoop installed
|
|
* 'hadoop' user created
|
|
|
|
See :doc:`hadoop-swift` for information on using Swift with your sahara cluster
|
|
(for EDP support Swift integration is currently required).
|
|
|
|
To support EDP, the following components must also be installed on the guest:
|
|
|
|
* Oozie version 4 or higher
|
|
* mysql
|
|
* hive
|
|
|
|
See :doc:`vanilla_imagebuilder` for instructions on building images for this
|
|
plugin.
|
|
|
|
Hortonworks Plugin Requirements
|
|
-------------------------------
|
|
|
|
This plugin does not have any additional requirements. Currently, only the
|
|
CentOS Linux distribution is supported but other distributions will be
|
|
supported in the future.
|
|
To speed up provisioning, the HDP packages can be pre-installed on the image
|
|
used. The packages' versions depend on the HDP version being used.
|
|
|
|
Cloudera Plugin Requirements
|
|
----------------------------
|
|
|
|
Cloudera Plugin does not have any additional requirements, just build a CDH
|
|
image to deploy the cluster.
|
|
|
|
See :doc:`cdh_imagebuilder` for instructions on building images for this
|
|
plugin.
