JiangJiafu commented on ZOOKEEPER-2800: --------------------------------------- I have a quick look to the 2355, I am not pretty sure these are the same PR. But from the log I can see that zk1(the problem node) do lost connection to the leader while wring data, and then many transcations are lost too(including the closeSession transcation). > zookeeper ephemeral node not deleted after server restart and consistency is > not hold > ------------------------------------------------------------------------------------- > > Key: ZOOKEEPER-2800 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2800 > Project: ZooKeeper > Issue Type: Bug > Components: quorum > Affects Versions: 3.4.11 > Environment: Centos6.5 java8 > Reporter: JiangJiafu > Priority: Critical > Attachments: zoo.cfg, zookeeper2.out, zookeeper3.out, zookeeper.out > > > I deploy a cluster of ZooKeeper with three nodes: > ofs_zk1:30.0.0.72 > ofs_zk2:30.0.0.73 > ofs_zk3:30.0.0.99 > On 2017-06-02, use the c zk client to create some ephemeral sequential nodes,: > /adm_election/rolemgr/rolemgr0000000008, > /adm_election/rolemgr/rolemgr0000000011, > /adm_election/rolemgr/rolemgr0000000012, > with sesstion timeout 20000 ms. > Then I restart ofs_zk1 and ofs_zk2. > On 2017-06-05, I found that, these ephemeral nodes still exist on ofs_zk1. > I can check the nodes by zkCli.sh get command on ofs_zk1. > But these nodes doesn't not exist on ofs_zk2 and ofs_zk3. > Is it odd? > I have upload the whole deploy directory of three nodes to: > https://pan.baidu.com/s/1miohiCo , > The log is printed in log/zookeeper.out > log of ofs_zk3 is too large, so I only show the head 1000 lines. > Since I find this PR a little late, some snapshot and log may be deleted. > I hope anyone can help find the reason. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
