[jira] [Commented] (BOOKKEEPER-629) Support hostname based ledger metadata to help users to change IP with existing installation

["Sijie Guo (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BOOKKEEPER-629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13917790#comment-13917790 ] 

Sijie Guo commented on BOOKKEEPER-629:
--------------------------------------

the patch looks good. but after thinking a bit more, the try catch logic to search both ip and hostname znodes is not good enough for extending in future, if we want to support other id for bookie id in future. so I am kind of thinking we should do as below:

- if there is any cookie files in the local directory, we should use bookieHost in the cookie file as bookie id (znode path) to check, regarding the settings in configuration.
- if there is no cookie files in local directory, we use the settings in the configuration to decide whether using ip or address as bookie id.

> Register the bookie with *hostname:port* and also store the bookie addresses as *hostname:port* in ledger metadata files instead of *ip:port*
> This will help users to change the machine IP if they want without loosing their data.
> Supporting hostname based installation/functionality is one of the important requirement of users.
> Any thoughts?
