### Motivation Right now, MetadataStore returns `BadVersion` error when node already exists instead `AlreadyExists` error-code. There are many usecases which require correct error code to handle failures. for example: [partitioned-topic](https://github.com/apache/pulsar/blob/master/pulsar-broker/src/main/java/org/apache/pulsar/broker/admin/AdminResource.java#L291) considers `AlreadyExists` error as successful result but instead metadata-api returns `BadVersion` error which creates complication while handling failures. So, return correct error-code(`AlreadyExists`) if node already exists while creating metadata key-placeholder, ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
