[jira] [Commented] (SOLR-12716) NodeLostTrigger should support deleting replicas from lost nodes

["Shalin Shekhar Mangar (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-12716?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16604142#comment-16604142 ] 

Shalin Shekhar Mangar commented on SOLR-12716:
----------------------------------------------

# Adds {{preferredOperation}} parameter to {{NodeLostTrigger}} with only two possible values being {{MOVEREPLICA}} (default) and {{DELETENODE}}
# {{ComputePlanAction}} is modified to create a {{DeleteNodeSuggester}} for each lost node one at a time when the preferredOperation=deletenode.
# New test {{ComputePlanActionTest.testNodeLostTriggerWithDeleteNodePreferredOp}}

I'll commit once precommit and tests pass.

> NodeLostTrigger only moves replicas from the lost node to other nodes in the cluster. We should add a way to delete replicas of the lost node from the cluster state.
