CRITICAL FINDING: Metadata responses are CORRECT! Verified: ✅ handleMetadata being called ✅ Topics include _schemas (the required topic) ✅ Broker information: nodeID=1339201522, host=kafka-gateway, port=9093 ✅ Response size ~117 bytes (reasonable) ✅ Response is being generated without errors IMPLICATION: The problem is NOT in Metadata responses. Since Schema Registry client has: 1. ✅ Received Metadata successfully (_schemas topic found) 2. ❌ Never sends ListOffsets requests 3. ❌ Never sends Fetch requests 4. ❌ Never sends consumer group requests The issue must be in Schema Registry's consumer thread after it gets partition information from metadata. Likely causes: 1. partitionsFor() succeeded but something else blocks 2. Consumer is in assignPartitions() and blocking there 3. Something in seekToBeginning() is blocking 4. An exception is being thrown and caught silently Need to check Schema Registry logs more carefully for ANY error/exception or trace logs indicating where exactly it's blocking in initialization.
