>
> LeaderInitiatedRecoveryThread looks at a random replica to figure out if it
> should re-publish LIR state to "down". It does however publish the LIR state
> for the correct replica.
> The bug has always been there. The thread used ZkStateReader.getReplicaProps
> method with the coreName to find the correct replica. However, the coreName
> parameter in getReplicaProps was un-used and I removed it in SOLR-6240 but I
> didn't find and fix this bug then.
> The possible side-effects of this bug would be that we may be republish LIR
> state multiple times and/or in rare cases, cause double 'requestrecovery' to
> be executed on a replica.
