The following actions results in this issue. 1. handle_1 gets the current log 2. ReplicaAlterLogDirsThread replaces current log by future log 3. handle_1 set the new hw to “current” log but the log is actually invalid The solution is that the action 1 and 3 must be executed within same read lock of leaderIsrUpdateLock to avoid adding new hw to invalid log (which is replaced by ReplicaAlterLogDirsThread) **Test Plan** Relying on ```PlaintextAdminIntegrationTest.testAlterReplicaLogDirs```. I have looped the test with this patch 100 times. all pass ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
