1.2. HDP Public Properties

You can set the following properties when you run msiexec:

Table 3.1. Property value information

Property	Mandatory?	Value	Associated Value(s) in Cluster Properties file	Description
DESTROY_DATA	Y	Yes or No	none	Specify `No` to keep existing data from previous installation. `No` does not format the NameNode. Specify `Yes` to remove all existing or previous HDP data and format the NameNode, creating an installation with a clean data slate.
HDP_USER_PASSWORD	Y	password	none	Password defined when creating the Hadoop user. Note that if the password does not meet your password policy standards, the installation will fail.
HDP_LAYOUT	Y	clusterproperites_ full_path	none	Absolute path to the Cluster Properties file. Note that relative paths are not supported and the path may not contain spaces. For example, c:\MSI_Install\clusterproperties.txt.
HDP_DIR	N	install_dir	none	Absolute path to the Hadoop root directory where HDP components are installed.
HDP	N	Yes or No		Setting this to `Yes` instructs the MSI to install optional HDP components such as Flume, HBase, Knox, Falcon and Storm. When enabled, you must specify the components on the command line; for example: `HDP="YES" KNOX="YES" KNOX_SECRET="secret" FALCON="NO" HBASE="YES" FLUME="NO" STORM="NO"`. Excluding the optional components from the command line causes the installation to fail.
FLUME	N	Yes or No	FLUME_HOSTS	Includes the installation of Flume components on the hosts matching the name defined in the cluster properties file.
HBASE	N	Yes or No	HBASE_MASTER HBASE_REGIONSERVERS	Includes the installation of HBase components on the hosts matching the name defined in the cluster properties file.
KNOX	N	Yes or No	KNOX_HOST	Includes the installation of Knox gateway on the host matching the name defined in the cluster properties file. When yes, the `KNOX_SECRET` must also be specified as a parameter.
KNOX_MASTER_SECRET	N	secret	none	Specified only when `KNOX="YES"`. The master secret to protect Knox security components, such as SSL certificates.
FALCON	N	Yes or No	FALCON_HOSTS	Includes the installation of the Falcon components on the host matching the name defined in the cluster properties file.
STORM	N	Yes or No	STORM_NUMBER STORM_SUPERVISORS	Includes the installation of the Storm components on the host matching the name defined in the cluster properties file.
RANGER	N	Yes or No	RANGER_HOST	Includes the installation of the Ranger Admin and User Sync components on the host matching the name defined in the cluster properties file.
SPARK	N	Yes or No	SPARK_JOB_SERVER SPARK_HIVE_METASTORE	Includes the installation of the Spark components on the host matching the name defined in the cluster properties file.

For optional HDP Components such as Knox and Falcon, include HDP=yes and specify "yes" or "no" for the components you would like to install or not, respectively. For example: FLUME=no HBASE=yes KNOX=no FALCON=no STORM=no.

This command needs to run in the command-line interface of each node in your cluster. If you are not installing any optional components, specify HDP=no.

Components are only installed if the host name matches a value in the cluster properties file. For examples of msiexec commands, see Option 3: Installing HDP from the Command Line.
