[PR] CASSANDRA-21426: AssertionError in hasReplicaWithOngoingRepair when parallel_repair_count > 1 [cassandra]
patrickclee0207 opened a new pull request, #4858:
URL: https://github.com/apache/cassandra/pull/4858
An assetion error is thrown from AutoRepairUtils.java when calling StorageService.instance.getTokenMetadata(). works fine when only 1 node is allowed parallel_repair_count: 1. When you increase this > 1 you start getting the assertion error
the change is to instead use StorageService.instance.getTokenMetadata().cachedOnlyTokenMap()
patch by Patrick Lee; reviewed by TBD for [CASSANDRA-21426](https://issues.apache.org/jira/browse/CASSANDRA-21426)
using CCM and 9 nodes, with the auto-repair config
```
auto_repair:
enabled: true
repair_check_interval: 30s
repair_task_min_duration: 5s
repair_type_overrides:
incremental:
enabled: true
min_repair_interval: 1m
global_settings:
parallel_repair_count: 3
allow_parallel_replica_repair: false
```
you can reproduce and get the assertion error. running the same in CCM with the patched version validates that there are no assertion errors and there were 2 nodes running incremental repairs concurrently.
