1、I tried to update partition num of a topic, but got error:

17:48:04.492 [AsyncHttpClient-7-1] WARN  org.apache.pulsar.client.admin.internal.BaseResource - [http://localhost:8080/admin/v2/persistent/public/default/341p/partitions?updateLocalTopicOnly=false] Failed to perform http post request: javax.ws.rs.InternalServerErrorException: HTTP 500 Internal Server Error
HTTP 500 Internal Server Error

Reason: HTTP 500 Internal Server Error

2、When I attempted to try update partition once again, i got below error:

Already have non partition topicpersistent://public/default/113p-partition-1 which contains partition suffix '-partition-' and end with numeric value and end with numeric value smaller than the new number of partition. Update of partitioned topic 3p could cause conflict.
