Vishal K commented on ZOOKEEPER-822: ------------------------------------ Hi Flavio, Ah! my trunk is quite old then. But I don't think it is necessary to run with the latest code for debugging this issue. I have identified one problem in WorkerSender.process(). This function calls manager.toSend() whicih calls connectOne. connectOne does a blocking connect (which takes order of minutes to return if a node is down). Thus, WorkerSender.run() will block and not send any successive notifications to other nodes. Let met know what you think I tired with adding timeouts to connectOne, but I am running into similar issue somewhere else. So that didnt fix the problem > Leader election taking a long time to complete > ----------------------------------------------- > > Key: ZOOKEEPER-822 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-822 > Project: Zookeeper > Issue Type: Bug > Components: quorum > Affects Versions: 3.3.0 > Reporter: Vishal K > Priority: Blocker > Attachments: 822.tar.gz, rhel.tar.gz, test_zookeeper_1.log, > test_zookeeper_2.log, zk_leader_election.tar.gz > > > Created a 3 node cluster. > 1 Fail the ZK leader > 2.

Repeat > After a few rounds leader election takes anywhere 25- 60 seconds to finish. > Note- we didn't have any ZK clients and no new znodes were created. > zoo.cfg is shown below: > #Mon Jul 19 12:15:10 UTC 2010 > server.1=192.168.4.12\:2888\:3888 > server.0=192.168.4.11\:2888\:3888 > clientPort=2181 > dataDir=/var/zookeeper > syncLimit=2 > server.2=192.168.4.13\:2888\:3888 > initLimit=5 > tickTime=2000 > I have attached logs from two nodes that took a long time to form the cluster > after failing the leader. The leader was down anyways so logs from that node > shouldn't matter. > Look for "START HERE". Logs after that point should be of our interest. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
