SOLR-13141: CDCR bootstrap does not replicate index to the replicas of target
cluster.
The leader node on the target cluster will now increment its term after
bootstrap succeeds so that all replicas of this leader are forced to recover
and fetch the latest index from the leader.

> Key: SOLR-13141
> URL: https://issues.apache.org/jira/browse/SOLR-13141
> Project: Solr
> Issue Type: Bug
> Components: CDCR
> Affects Versions: 7.5, 7.6
> Environment: This is system independent problem - exists on windows
> and linux - reproduced by independent developers
> Reporter: Krzysztof Watral
> Assignee: Shalin Shekhar Mangar
> Priority: Critical
> Fix For: master (9.0), 8.3
>
> Attachments: SOLR-13141.patch, SOLR-13141.patch, type 1 - replication
> wasnt working at all.txt, type 2 - only few documents were being
> replicated.txt
>
>
> i have encountered some problems with CDCR that are related to the value of
> {{replicationFactor}} param.
> I ran the solr cloud on two datacenters with 2 nodes on each:
> * dca:
> ** dca_node_1
> ** dca_node_2
> * dcb
> ** dcb_node_1
> ** dcb_node_2
> Then in sequence:
> * I configured the CDCR on copy of *_default* config set named
> *_default_cdcr*
> * I created collection "customer" on both DC from *_default_cdcr* config set
> with the following parameters:
> ** {{numShards}} = 2
> ** {{maxShardsPerNode}} = 2
> ** {{replicationFactor}} = 2
> * I disabled cdcr buffer on collections
> * I ran CDCR on both DC
> CDCR has started without errors in logs. During indexation I have encountered
> problem [^type 2 - only few documents were being replicated.txt], restart
> didn't help (documents has not been synchronized between DC )
> Then:
> * I stopped CDCR on both DC
> * I stopped all solr nodes
> * I restarted zookeepers on both DC
> * I started all solr nodes one by one
> * few minutes later I stared CDCR on both DC
> * CDCR has starded with errors (replication between DC is not working) -
> [^type 1 - replication wasnt working at all.txt]
> {panel}
> I've also discovered that problems appears only in case, when the
> {{replicationFactor}} parameter is higher than one
