I am newbie to Apache Manifold (ver – 2.12) and Solr(ver – 7.6) with Zookeeper (ver 3.14). I have created three collections in Solr out of which data for two comes from Manifold while one has from manual data insert through simple solr API. When I run jobs in Manifold I can see data is getting inserted in Solr and can be seen by querying Solr.
But when I restart solr all the shards and replicas goes down and do not recover ever. Also, I am unable to reload the collection as it always gives timeout error. I tried to take index backup and then try to restore it but restoring also fails with timeout error. I tried this reload command, restore command from the same server in which they are installed but still it fails. Looks like problem is only with the collections in which data is coming from Manifold as my other collection where I insert data via Solr API starts properly after restart. I don’t see any error getting logged in solr logs properly. I am not getting if I missed anything while doing configurations or there is some kind of lock on solr due to which none of the reload, restore commands works properly and on restarting solr I lose everything. Please suggest. Regards, Swapnil
