Subject [jira] [Commented] (SOLR-9555) Recovery can hang if a node is put into LIR as it is starting up
Date Thu, 19 Jan 2017 13:47:26 GMT

    [ https://issues.apache.org/jira/browse/SOLR-9555?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15829955#comment-15829955

Shalin Shekhar Mangar commented on SOLR-9555:
---------------------------------------------

I agree with Dat that "only set DOWN if current state is ACTIVE" is the wrong solution because
it has the potential to lose updates. Recovery process is guaranteed to bring a replica up
to date only if all updates after a hard commit make it to the replica's buffered log. Whether
the state of the replica is already RECOVERING or not makes no difference. If the leader is
not able to send an update then that guarantee cannot be made and therefore it is safest to
restart the recovery process.
