Research direction
Locate the HoodieGauge class in the Hudi codebase, likely under `org.apache.hudi.metrics`. Examine its implementation and usage. Then study the Dropwizard Metrics library's SettableGauge interface (available from version 4.2.0). The goal is to replace all instances of HoodieGauge with SettableGauge, ensuring backward compatibility. The issue references a JIRA ticket with more details; review that for specific requirements.
