Replacement Patterns

To have HIVE-{uuid} application name instead of many unique names:

1. Put replacement\npattern\n lines to patterns.txt file:

{uuid}
[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}

2. Specify --patterns argument:

yarn-apps-exporter http://resource.manager.hostname:8088 --patterns patterns.txt
