[Bug]: Double leader result in an abnormal table status

rfyu opened this issue · comments

commented

What happened?

When two AMS both consider themselves as leaders, there is a high likelihood of the table optimization status being overridden.
image
Using "ods_fuxi_ubt_server_data_di" as a case：

  1. ams1 assigns two tasks to the optimizer
  2. task1 is completed, and ams1 receives the status report
  3. ams1 loses connection with ZooKeeper, but does not lose leadership
  4. ams2 gets leadership and initializes based on MySQL information
  5. task2 completed, and ams1 receives the status report, then changes ods_fuxi_ubt_server_data_di status to committing
  6. ams1 is committing a new snapshot
  7. ams1 lost leadership
  8. ods_fuxi_ubt_server_data_di commit fails, and its status is changed to idle
  9. during the refresh process, ams2 discovers a new snapshot being generated and mistakenly replaces the idle status with the running status, resulting in an abnormal state

Root cause：
