Subject [jira] [Updated] (SOLR-3125) When a SolrCore registers in zk there may be stale leader state in the clusterstate.json.
Date Sun, 12 Feb 2012 01:16:59 GMT

     [ https://issues.apache.org/jira/browse/SOLR-3125?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mark Miller updated SOLR-3125:
------------------------------

    Attachment: SOLR-3125.patch

a workaround - on registering, instead of getting the leader from the cluster state, we go
right to the ephemeral zk node

> This can be a problem when stop the whole cluster and then start it - a leader that has
not yet showed up in the cluster state may see a stale leader and try to recover from it.
