Description
Build : 5.5.0-2954 (RC3)
Test : -test tests/2i/test_idx_rebalance_replica_vulcan_kv_opt.yml -scope tests/2i/scope_idx_rebalance_replica_vulcan_new.yml
Iteration : 2 (~15 hrs of test run)
In the system test, there are steps to rebalance in and out the data nodes. As per the fix for MB-29937 (https://github.com/couchbase/indexing/commit/933727fc4a114bb9e73e30f26072af5a6d0a69b5), If the rebalance operation doesnt involve an indexer node, the indexes should not be rebalanced. But in this case, the indexes are still getting rebalanced and replicated. The replication also is either stuck or very slow, causing the rebalance to be stuck at 99.1% since 10+ hrs now.

The indexer logs are filled with following errors :

Here, 172.23.96.207 is the kv node that is being rebalanced out.
Marking this issue as a regression since we had successfully completed 3 iterations of the same test on RC1 build.
