Build:7.0.0-4584

Test: -test tests/fts/cheshire-cat/test_fts_clusterops_cheshire_cat_coll_crud.yml -scope tests/fts/cheshire-cat/scope_fts_cheshire_cat.yml
Test Cycle: 1

In the test,

• there are 5 buckets, out of which 20 static fts indexes are created on collections of 3 buckets. Mutations are going on these collections
• For the collections on other 2 buckets, we create and drop indexes and no mutations are going on these collections.
• Continuously run queries on the indexes of collections of bucket1 and bucket2
• wait for 15 mins
• kill cbft on 172.23.97.217 and wait for 15 mins
• stop all mutations and wait for 10 mins
• add fts node 172.23.107.4 and start rebalance and wait for 15 mins
• stop create index loop on bucket4 and bucket5
• wait for rebalance to complete
• Once rebalance is complete, kill cbft on 172.23.107.5 and wait for 15 mins
• start mutations on the collections of bucket1, bucket2 and buckt3
• wait for 2 mins and rebalance to remove node 172.23.97.232 and wait for 5 mins
• kill memcached on 172.23.97.237 and wait for 15 mins
• Add data node 172.23.97.232 and rebalance and wait for 10 mins
• kill cbft on 172.23.107.5 ( which was at 2021-02-22T14:33:48-08:00) and wait for 15 mins
• Rebalance out fts node : 172.23.97.217

Rebalance fails with below:
