Evict leader could be paused after upgrading #9416
Description
Bug Report
What did you do?
Use the version before v8.5.x:
tiup playground v8.1.0 --tiflash 0 --pd 1 --kv 4 --host 10.2.8.101 --tag test
» scheduler add evict-leader-scheduler 1
Success! The scheduler is created.
» scheduler config evict-leader-scheduler
{
"store-id-ranges": {
"1": [
{
"start-key": "",
"end-key": ""
}
]
}
}
Upgrade to v8.5.x:
tiup playground v8.5.2 --tiflash 0 --pd 1 --kv 4 --host 10.2.8.101 --tag test
» scheduler config evict-leader-scheduler
{
"store-id-ranges": {
"1": [
{
"start-key": "",
"end-key": ""
}
]
},
"batch": 0
}
The batch will be changed to 0, which leads to the evict-leader-scheduler not work.
Workaound:
- delete the scheduler and add it again
- or pd-ctl
scheduler config evict-leader-scheduler set batch 3
What version of PD are you using (pd-server -V)?
