-----------------------------------
Summary: Leader may skip publish itself as ACTIVE when its last
published state is DOWN
Key: SOLR-12214
URL: https://issues.apache.org/jira/browse/SOLR-12214
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Cao Manh Dat
Assignee: Cao Manh Dat
Found this problem on beasting LeaderVoteWaitTimeout,
* a replica publish itself as DOWN on RecoveryStrategy.pingLeader()
* It won the election (by vote wait timeout) then skipping publish itself as
ACTIVE (by looking into clusterstate, its state still ACTIVE).
* ends up with a leader with DOWN state!
Therefore, replica should look into both clusterstate and its local last
published state.
