**Is your feature request related to a problem? Please describe.** Current Helix keeps 3 kinds of participant information: 1. Instance config 2. Instance metadata such as current state and history 3. Live instance info (ephemeral node) The real host info is mostly with the live instance node only. However, once a host is replaced by a different one, we lose the information that are stored in the live instance node. For example, if user is using a "logical host name" as the participant name (such as "Participant_A"), then once the host is replaced, we won't be able to tell which host has been used for Participant_A before. Given this, we propose add more information, such as the real host name into the HISTORY znode. **Describe the solution you'd like** HISTORY node shall contain more information if they present in the live instance node. To resolve this ticket, we shall at least include the real host name in the HISTORY node. **Additional context** Add any other context or screenshots about the feature request here. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
