Rebalance fails with "Client.Timeout exceeded while awaiting headers"

1) Create a 3 node cluster : 1 kv, 1 indexer and 1 n1ql

2) Create multiple secondary indexes(around 50+ on my vagrant VM's). All the indexes are hosted on indexer1 node.

3) Add one more indexer node , lets say indexer2 and start rebalance. Indexes won't be redistributed to indexer2(as per design) after rebalance completes.

4) Remove indexer1 and start rebalance again.

Run queries, create indexes, build indexes and drop indexes in parallel.

Rebalance failed with

{service_rebalance_failed,index, {rebalance_failed, {service_error, <<"Post http://127.0.0.1:9102/dropIndex: net/http: request canceled (Client.Timeout exceeded while awaiting headers)">>}}}

Another important thing to note is that rebalance issues don't get fixed by running "curl  -u Administrator:password http://index_node:9102/cleanupRebalance" on both the indexer nodes.
