Richard Coggins commented on SOLR-8587:
---------------------------------------
Same as previous comment, I just upgraded Solr to 5.5 and noticed that
/solr/admin/cores API stopped working with the following exception:

> Add segments file information to core admin status
> --------------------------------------------------
>
> Key: SOLR-8587
> URL: https://issues.apache.org/jira/browse/SOLR-8587
> Project: Solr
> Issue Type: Improvement
> Reporter: Shai Erera
> Assignee: Shai Erera
> Fix For: 5.5, master
>
> Attachments: SOLR-8587.patch, SOLR-8587.patch
>
>
> Having the index's segments file name returned by CoreAdminHandler STATUS can
> be useful. The info I'm thinking about is the segments file name and its
> size. If you record that from time to time, in a case of crisis, when u need
> to restore the index and may not be sure which copy you need to restore, this
> tiny piece of info can be very useful, as the segmentsN file records the
> commit point, and therefore what you core reported and what you see at hand
> can help you make a safer decision.
> I also think it's useful info in general, e.g. probably even more than
> 'version', and it doesn't add much complexity to the handler or the response.
