Troubleshooting SeaTunnel Cluster Split-Brain: A Deep Dive into Hazelcast Configuration and GC-Induced Failures

The article delves into troubleshooting SeaTunnel cluster split-brain phenomena related to Hazelcast configuration and GC-induced failures.
The cluster consisted of 3 Alibaba Cloud ECS servers using a static slot mode with specific memory configurations.
Issues like split-brain occurrences, master and worker node problems, and cluster unavailability were traced back to network setup failures and full GC-induced delays.
Solutions included optimizing the ST cluster heartbeat timeout and GC configurations to prevent split-brain instances and improve cluster stability.
GC optimizations involved adjusting parameters like MaxGCPauseMillis, GCTimeRatio, G1ReservePercent, and ConcurrentGCThreads.
JVM tuning parameters were refined progressively to enhance memory reclamation efficiency and reduce occurrences of Full GCs.
Despite a slight impact on application throughput, the optimized configurations led to the eradication of split-brain incidents and improved system health.
Through the adoption of community recommendations and fine-tuning JVM parameters, the stability of the cluster was maintained during critical operational periods.
The article emphasizes the need for meticulous configuration adjustments to address cluster split-brain scenarios and optimize system performance in distributed environments.
By implementing detailed GC optimizations and failure detection configurations, the SeaTunnel cluster achieved increased resilience and stability.
Continuous monitoring, log analysis, and parameter tuning played a vital role in resolving cluster issues and ensuring the seamless operation of the system.
