How do I solve a "failed to resolve address" error after upgrading the Events Service to 4.3?

[#1]

Symptoms

The Events Service does not start after upgrading from version 4.2 to version 4.3.

The following error message appears in events-service/logs/events-service-api-store.log:

1) Error injecting constructor, java.lang.IllegalArgumentException: Failed to resolve address for [10.132.1.114[9300-9400]]

Diagnosis

Following the steps in the Upgrade the Events Service documentation, the user moves the data directory and copies all properties in the events-service-api-store.properties file located in the events-service/conf/ directory to the new config directory.

The user then sees the following error after starting the Events Service:

1) Error injecting constructor, java.lang.IllegalArgumentException: Failed to resolve address for [10.132.1.114[9300-9400]]

This is due to a change in the value of the property ad.es.node.unicast.hosts within the properties file in version 4.3.

Version 4.2 example

ad.es.node.unicast.hosts=node1.example.com[9300-9400],node2.example.com[9300-9400],node3.example.com[9300-9400]

Version 4.3 example

ad.es.node.unicast.hosts=node1.example.com:9300,node2.example.com:9300,node3.example.com:9300

Solution

Do not enter a range for the ad.es.node.unicast.hosts property when copying and pasting old properties into the new property file.  

Instead of: 

node1.example.com[9300-9400]

Enter: 

node1.example.com:9300
