There are 2 cluster of Cassandra Test1 & Test2(both has same version & config). Need to backup keyspace present on solr enable node of test1 cluster and restore same to solr enable node of Test2 cluster. Post restoring keyspace we need to create core & perform indexing again is there any way to avoid re indexing post restoration please let us know what files should we copy from test1 cluster to test2 cluster to achieve same.
[EDIT] I have tried following
1) Created keyspace ks1 on test2 cluster on node using schema of ks on test1 node 2 then Copied keyspace data from test1 cluster node 2 datafolder: /var/lib/cassandra/data/ks1/*
2) also copied solr.data/ks1.table/index to test 2 node
3)restarted service post this activity
4) ks working fine able to query data
5) but cores are not there in solr which were created for ks on node 1(test1) checked logs there was error unable to initialize core as resources schema.xml & are not present did you missed to upload it ? Please let me know from which folder i can copy this resources from node(test1)) and keep in test2 so that i can avoid skip core creation and reindexing again on test2 cluster for ks keyspace.
I havent used sstableloder copied data directly using scp and saved in destination ks data directory .
Dse Version : 5.0.7
Alao let me know if it is must to perform reindexing post restoring backup of dse search node on another search node.
