@YKG sorry for this accident, we will fix it ASAP.
@you06 something wrong with this challenge issue, PTAL.

@you06 @breeswish Just want to confirm if there anyone is working on this issue? If no one is working on this now, I want to try to fix it.

Accroding to my investigation, the root cause is the incorrect implementation of the function savePartition. Maybe the key is in this line . I tried with tiup playground, and that line will keep overwriting other service's partitionMap if multi services running on the same host.

Good catch, there is no one working on this.
