lucaspeng12138 opened a new issue, #5567:
URL: https://github.com/apache/inlong/issues/5567

   ### What happened
   
   Master start failed with NullPointerException.
   
   java.lang.NullPointerException: null
   	at io.prometheus.client.CollectorRegistry.collectorNames(CollectorRegistry.java:119) ~[simpleclient-0.14.1.jar:?]
   	at io.prometheus.client.CollectorRegistry.register(CollectorRegistry.java:50) ~[simpleclient-0.14.1.jar:?]
   	at io.prometheus.client.Collector.register(Collector.java:308) ~[simpleclient-0.14.1.jar:?]
   	at io.prometheus.client.Collector.register(Collector.java:301) ~[simpleclient-0.14.1.jar:?]
   	at org.apache.inlong.tubemq.server.master.stats.prometheus.MasterPromMetricService.start(MasterPromMetricService.java:52) ~[tubemq-server-1.3.0-SNAPSHOT.jar:1.3.0-SNAPSHOT]
   	at org.apache.inlong.tubemq.server.master.TMaster.<init>(TMaster.java:219) ~[tubemq-server-1.3.0-SNAPSHOT.jar:1.3.0-SNAPSHOT]
   	at org.apache.inlong.tubemq.server.tools.MasterStartup.main(MasterStartup.java:44) ~[tubemq-server-1.3.0-SNAPSHOT.jar:1.3.0-SNAPSHOT]
   
   ### What you expected to happen
   
   Master start normally.
   
   ### How to reproduce
   
   File: inlong-tubemq/tubemq-server/src/main/java/org/apache/inlong/tubemq/server/master/stats/prometheus/MasterPromMetricService.java
   Caused by _start()_ function, _register()_ will use mfs which is returned from _collect()_. And when tubemq-master start, _collect()_ will return null. Then NullPointerException happens.
   
   ### Environment
   
   _No response_
   
   ### InLong version
   
   master
   
   ### InLong Component
   
   InLong TubeMQ
   
   ### Are you willing to submit PR?
   
   - [ ] Yes, I am willing to submit a PR!
