Solr cores issue
Hello,
Suppose I have several cores in a single webapp ,I have issue with Index
beong corrupted in one core ,or schema /solrconfig of one core is not well
formed ,then entire webapp refused to load on server restart?
Why does this happen?
Regards
Sujatha

Isn't it administratively easier with multiple cores instead of multiple
webapps??

It might be administratively easier to have multiple webapps, but
it shouldn't really matter as far as I know...

yes ,I must have mis-copied and yes, i do have the conf folder per core
with schema etc ...
Because of this issue ,we have decided to have multiple webapps with about
50 cores per webapp ,instead of one singe webapp with all 200 cores ,would
this make better sense ?
what would be your suggestion?

Shouldn't be. What do your log files say? You have to treat each
core as a separate index. In other words, you need to have a core#/conf
with the schema matching your core#/data/index directory etc.
I suspect you've simply mis-copied something.

I was migrating to cores from webapp ,and I was copying a bunch of indexes
from webapps to respective cores ,when I restarted ,I had this issue where
the whole webapp with the cores would not startup and was getting index
corrupted message..
In this scenario or in a scenario where there is an issue with schema
/config file for one core ,will the whole webapp with the cores not restart?

Index corruption is very rare, can you provide more details how you
got into that state?
