> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: hdfs, SolrCloud
> Reporter: Shalin Shekhar Mangar
> Priority: Major
>
> MoveReplica API for shared file systems attempts to delete the old replica
> and then creates a new replica (with same core and coreNode name) on the
> target node. If the overseer fails between the two operations then the
> replica is lost. The API should detect that if the source is not live, it
> only needs to create the new replica. Then the old replica (upon coming back
> online) auto-detects a replacement and unloads itself. This is also how
> OverseerAutoReplicaFailoverThread works today.
