Configuring TLS/SSL for HBase

Minimum Required Role: Configurator (also provided by Cluster Administrator, Full Administrator)

Before You Begin:

Before enabling TLS/SSL, ensure that keystores containing certificates bound to the appropriate domain names will need to be accessible on all hosts on which at least one HBase daemon role is running.
Keystores for HBase must be owned by the hbase group, and have permissions 0440 (that is, readable by owner and group).
You must specify absolute paths to the keystore and truststore files. These settings apply to all hosts on which daemon roles of the HBase service run. Therefore, the paths you choose must be valid on all hosts.
Cloudera Manager supports the TLS/SSL configuration for HBase at the service level. Ensure you specify absolute paths to the keystore and truststore files. These settings apply to all hosts on which daemon roles of the service in question run. Therefore, the paths you choose must be valid on all hosts.
An implication of this is that the keystore file names for a given service must be the same on all hosts. If, for example, you have obtained separate certificates for HBase daemons on hosts node1.example.com and node2.example.com, you might have chosen to store these certificates in files called hbase-node1.keystore and hbase-node2.keystore (respectively). When deploying these keystores, you must give them both the same name on the target host — for example, hbase.keystore.

Configuring TLS/SSL for HBase Web UIs

The steps for configuring and enabling TLS/SSL for HBase are similar to those for HDFS, YARN and MapReduce:

Edit the following TLS/SSL properties according to your cluster configuration:

HBase TLS/SSL Properties
Property	Description
HBase TLS/SSL Server JKS Keystore File Location	Path to the keystore file containing the server certificate and private key used for encrypted web UIs.
HBase TLS/SSL Server JKS Keystore File Password	Password for the server keystore file used for encrypted web UIs.
HBase TLS/SSL Server JKS Keystore Key Password	Password that protects the private key contained in the server keystore used for encrypted web UIs.

Check the Web UI TLS/SSL Encryption Enabled property.

Web UI TLS/SSL Encryption Enabled Enable TLS/SSL encryption for the HBase Master, RegionServer, Thrift Server, and REST Server web UIs.
Click Save Changes to commit the changes.
Restart the HBase service.

Go to the HBase service
Click the Configuration tab.
Select Scope > HBase REST Server.
Select Category > Security.
In the Search field, type TLS/SSL REST to show the HBase REST TLS/SSL properties.

Edit the following TLS/SSL properties according to your cluster configuration:

Property	Description
Enable TLS/SSL for HBase REST Server	Encrypt communication between clients and HBase REST Server using Transport Layer Security (TLS).
HBase REST Server TLS/SSL Server JKS Keystore File Location	The path to the TLS/SSL keystore file containing the server certificate and private key used for TLS/SSL. Used when HBase REST Server is acting as a TLS/SSL server. The keystore must be in JKS format.file.
HBase REST Server TLS/SSL Server JKS Keystore File Password	The password for the HBase REST Server JKS keystore file.
HBase REST Server TLS/SSL Server JKS Keystore Key Password	The password that protects the private key contained in the JKS keystore used when HBase REST Server is acting as a TLS/SSL server.

Go to the HBase service
Click the Configuration tab.
Select Scope > HBase Thrift Server.
Select Category > Security.
In the Search field, type TLS/SSL Thrift to show the HBase Thrift TLS/SSL properties.

Edit the following TLS/SSL properties according to your cluster configuration:

Property	Description
Enable TLS/SSL for HBase Thrift Server over HTTP	Encrypt communication between clients and HBase Thrift Server over HTTP using Transport Layer Security (TLS).
HBase Thrift Server over HTTP TLS/SSL Server JKS Keystore File Location	The path to the TLS/SSL keystore file containing the server certificate and private key used for TLS/SSL. Used when HBase Thrift Server over HTTP is acting as a TLS/SSL server. The keystore must be in JKS format.
HBase Thrift Server over HTTP TLS/SSL Server JKS Keystore File Password	The password for the HBase Thrift Server JKS keystore file.
HBase Thrift Server over HTTP TLS/SSL Server JKS Keystore Key Password	The password that protects the private key contained in the JKS keystore used when HBase Thrift Server over HTTP is acting as a TLS/SSL server.
