Configuring RMI JMX with Basic Authentication

To collect Java Management Extensions (JMX) data through a Remote Method Invocation (RMI) port that's secured with Basic Authentication, follow these steps:

Create the Override Configuration File (if it doesn't exist): Navigate to your cluster's directory and create an override.yml file if one isn't already present:

Bash
    
xxxxxxxxxx
 
touch $AcceloHome/work/<clusterName>/override.yml
Copy

Configure the override.yml File:
1. Open the override.yml file using a text editor:

Bash
    
xxxxxxxxxx
 
vi $AcceloHome/work/<clusterName>/override.yml
Copy

b. Insert the following configurations for the respective services, if they're not already included:

For Hive Metastore:

Bash
    
xxxxxxxxxx
 
jmx:    hive_metastore_auth: "true"    hive_metastore_username: "<HIVE METASTORE USERNAME>"    hive_metastore_password: "<HIVE METASTORE PASSWORD>"    hive_metastore_port: "<HIVE METASTORE JMX PORT>"
Copy

For Hive Server:

Bash
    
xxxxxxxxxx
 
jmx:    hive_server_auth: "true"    hive_server_username: "<HIVE SERVER USERNAME>"    hive_server_password: "<HIVE SERVER PASSWORD>"    hive_server_port: "<HIVE SERVER JMX PORT>"
Copy

For Kafka:

Bash
    
xxxxxxxxxx
 
jmx:        kafka_broker_auth: "true"    kafka_broker_username: "<KAFKA BROKER USERNAME>""    kafka_broker_password: "<KAFKA BROKER PASSWORD>""    kafka_broker_port: "<KAFKA BROKER JMX PORT>"
Copy

For Zeppelin:

Bash
    
xxxxxxxxxx
 
jmx:        zeppelin_master_auth: "true"    zeppelin_master_username: "<ZEPPELIN MASTER USERNAME>""    zeppelin_master_password: "<ZEPPELIN MASTER PASSWORD>"    zeppelin_master_port: "<ZEPPELIN MASTER JMX PORT>"
Copy

For Zookeeper:

Bash
    
xxxxxxxxxx
 
jmx:    zookeeper_server_auth: "true"    zookeeper_server_username: "<ZOOKEEPER SERVER USERNAME>""    zookeeper_server_password: "<ZOOKEEPER SERVER PASSWORD>""    zookeeper_server_port: "<ZOOKEEPER SERVER PORT>"
Copy

For Kafka Mirror Maker:

Bash
    
xxxxxxxxxx
 
jmx:        kafka_mirror_maker_port: "<KAFKA MIRROR MAKER PORT>"    kafka_mirror_maker_auth: "true"    kafka_mirror_maker_username: "<KAFKA MIRROR MAKER USERNAME>"    kafka_mirror_maker_password: "<KAFKA MIRROR MAKER PASSWORD>"
Copy

c. Save your changes to the override.yml file.

d. Apply the new configuration by running the following command:

Bash
    
xxxxxxxxxx
 
accelo reconfig cluster
Copy

Configuring SSL for JMX RMI Port

To gather JMX data through an Secure Sockets Layer (SSL)-enabled RMI port, ensure the following procedure is adhered to, keeping in mind that all SSL certificates (truststores) must be identical across services with exposed JMX RMI ports.

Create the Override Configuration File: If the override.yml file doesn't exist within your cluster's workspace, create it:

Bash
    
xxxxxxxxxx
 
touch $AcceloHome/work/<clusterName>/override.yml
Copy

Configure the override.yml File:

a. Open the override.yml file for editing:

Bash
    
xxxxxxxxxx
 
vi $AcceloHome/work/<clusterName>/override.yml
Copy

b. Add the necessary SSL configuration for each specific service if not already present. Begin with the common configuration applicable to all services:

Common Configuration for All Services:

Bash
    
xxxxxxxxxx
 
jmx:    pulsejmx_use_ssl: true        pulsejmx_ssl_truststore: </PATH/TO/SERVICE/TRUSTORE/FILE>    pulsejmx_ssl_truststore_password: <SERVICE TRUSTSTORE PASSWORD>
Copy

For Hive Metastore:

Bash
    
xxxxxxxxxx
 
jmx:    hive_metastore_ssl: "true"
Copy

For Hive Server:

Bash
    
xxxxxxxxxx
 
jmx:    hive_server_ssl: "true"
Copy

For Zeppelin:

Bash
    
xxxxxxxxxx
 
jmx:    zeppelin_master_ssl: "true"
Copy

For Zookeeper:

Bash
    
xxxxxxxxxx
 
jmx:    zookeeper_server_ssl: "true"
Copy

For Kafka Mirror Maker:

Bash
    
xxxxxxxxxx
 
jmx:    kafka_mirror_master_ssl: "true"
Copy

c. Save the changes to the override.yml file.

d. Apply the new SSL configurations by running:

Bash
    
xxxxxxxxxx
 
accelo reconfig cluster
Copy
