Subject [jira] [Created] (SOLR-9199) ZkController#publishAndWaitForDownStates logic is inefficient
Date Wed, 08 Jun 2016 21:39:20 GMT
Hrishikesh Gadre created SOLR-9199:

             Summary: ZkController#publishAndWaitForDownStates logic is inefficient
                 Key: SOLR-9199
             Project: Solr
          Issue Type: Bug
            Reporter: Hrishikesh Gadre
            Assignee: Hrishikesh Gadre

The following logic introduced as part of SOLR-8720 is inefficient.


* foundStates flag is set to TRUE before the for loop.
* In the for loop we check if any replica on this node is not in the DOWN state. If yes, then
foundStates = FALSE
* If foundStates == TRUE then we break out of the loop and return.

The problem here is that once foundStates is set to FALSE, it is never reset to TRUE. Hence
we end up spending the whole 60 secs iterating over the collections even though all the replicas
are marked as DOWN in later iterations.
