Windows : Unable to add a new 7.0 node to a mixed mode cluster - pre_rebalance_janitor_run_failed

Details

    Description

      Steps to repro :
      1. Setup a 2-node cluster running 6.6.2-9588 with kv+n1ql+index+fts services on both nodes
      2. Install the sample buckets and create FTS indexes
      3. Swap rebalance node2 with a spare node running 7.0.0-5016.
      4. The cluster will now be in mixed mode
      5. Add a new 7.0 node to the cluster.

      The rebalance fails with error : 

      Rebalance exited with reason {pre_rebalance_janitor_run_failed,
      		 
      "travel-sample",
      		 
      {error,wait_for_memcached_failed,
      		 
      ['ns_1@172.23.107.142']}}.
      		 
      Rebalance Operation Id = fda046d63e6f8a8b8014af2288bb470a

      6. Retried the rebalance. That too failed as ns_server on the existing 7.0 node 172.23.107.142 has crashed with the following error - 

      Service 'ns_server' exited with status 1. Restarting. Messages:
