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

["Rakesh R (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BOOKKEEPER-629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13988790#comment-13988790 ] 

Rakesh R commented on BOOKKEEPER-629:
-------------------------------------

[~fpj] I understood the point. I took sometime on analysis, here I've noticed few impacts on Auto-Recovery module. What you all feel about the following case,
Auditor process sees the bookie availability by comparing(string comparison) the bookie Ids. Assume BK-1(4.2.x) acts as Auditor node and another BK-2 (4.2.x) node has upgraded to 4.3.0. Now Auditor will report BK-2 as unavailable and trigger ledger checks.

Thanks,
Rakesh

> 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?
