mvn clean install -Dmaven.test.skip.exec=trueHelix is a generic cluster management framework used for automatic management of partitioned, replicated and distributed resources hosted on a cluster of nodes. Helix provides the following features:
- Automatic assignment of resource/partition to nodes
- Node failure detection and recovery
- Dynamic addition of Resources
- Dynamic addition of nodes to the cluster
- Pluggable distributed state machine to manage the state of a resource via state transitions
- Automatic load balancing and throttling of transitions
The ignored job setting MaxForcedReassignmentsPerTask has been removed, including
JobConfig.Builder.setMaxForcedReassignmentsPerTask(int),
JobConfig.DEFAULT_MAX_FORCED_REASSIGNMENTS_PER_TASK, and its config enum entry.
Remove downstream API references and rebuild/release those callers before upgrading
them to this Helix version. MaxAttemptsPerTask continues to control task attempts;
retry, assignment, and TerminalStateExpiry behavior are unchanged.
New job configurations and job-ID copies no longer emit the retired key. Legacy raw records may still contain it: reading them does not rewrite them, and rebuilding them through the typed builder ignores the key. No stored-record migration is required, and this change does not add rejection of unknown fields to generic APIs.
Helix UI has been tested to run well on these versions of node and yarn:
"engines": {
"node": "~14.17.5",
"yarn": "^1.22.18"
},
