Subject [jira] [Commented] (SOLR-8587) Add segments file information to core admin status
Date Wed, 26 Oct 2016 18:05:58 GMT


Hrishikesh Gadre commented on SOLR-8587:

[~shaie] I ran into a similar problem (NoSuchFileException for the segments file) while working
on Solr backup/restore. This problem can be avoided by using the following trick implemented
in ReplicationHandler.

I see that LukeRequestHandler is not implementing similar strategy.

My guess is that if we change LukeRequestHandler to implement a strategy similar to ReplicationHandler,
it should fix the problem. Although I don't fully understand why is that the case. []
[~thetaphi] you have any idea?

> 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.
