-------------------------------------
Summary: Leader Election not respecting joinAtHead during ZK
Connection issues
Key: SOLR-16416
URL: https://issues.apache.org/jira/browse/SOLR-16416
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Houston Putman
OverseerRolesTest.testDesignatedOverseerRestarts has been failing consistently
(around 2.5% of the time). I think this is because LeaderElection.joinElection
does not respect the joinAtHead flag, if connectionIssues happen while setting
the leader election nodes.
LeaderElection does not use the automatic retryOnConnLoss flags when doing zk
operations. Instead, it waits for an error to come back, and it handles the
retry itself. This is fine for the normal case, because it checks if node is
represented in the leaderElection child nodes, and if so it ignores the
connection loss. However when doing joinAtHead, if the childNode exists, but
isn't at the place it should be, then the manual retry should be exercised.
