Varun Thacker commented on SOLR-12219:
--------------------------------------
You would need to explicitly create a trigger using an API . A user would
explicitly configure this .
Not sure if the syntax is correct but one would setup something like this with
autoscaling:
{code:java}
"set-trigger": {
"name" : "leaderless_shard_trigger",
"event" : "leaderLost",
"waitFor" : "300s",
"enabled" : true,
"actions" : [
{
"name" : "compute_plan",
"class": "solr.ComputePlanAction"
},
{
"name" : "execute_plan",
"class": "solr.ExecutePlanAction"
}
]
}
}{code}
> Autoscaling trigger to forceleader

> Key: SOLR-12219
> URL: https://issues.apache.org/jira/browse/SOLR-12219
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Components: AutoScaling
> Reporter: Varun Thacker
> Priority: Major
>
> In a scenario where a shard doesn't have a leader for an extended period of
> time, it would be nice if we can configure a trigger to fire a FORCELEADER
> API call
>
> FORCELEADER is the first step an ops person would fire today to come out of
> the leaderless shard scenario and if this could be automated then it would be
> useful for teams
