Henry Robinson updated ZOOKEEPER-1294: -------------------------------------- Attachment: ZOOKEEPER-1294-3.patch Ugh, forgot to switch from Cloudera copyright to Apache copyright header in Eclipse, which caused the RAT warning. This patch fixes that, and then we should be to go since all tests pass. Assuming this comes back clean again, I'll commit this. > One of the zookeeper server is not accepting any requests > --------------------------------------------------------- > > Key: ZOOKEEPER-1294 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1294 > Project: ZooKeeper > Issue Type: Bug > Components: server > Environment: 3 Zookeeper + 3 Observer with SuSe-11 > Reporter: amith > Assignee: kavita sharma > Fix For: 3.5.0 > > Attachments: ZOOKEEPER-1294-1.patch, ZOOKEEPER-1294-2.patch, > ZOOKEEPER-1294-3.patch, ZOOKEEPER-1294.patch > > > In zoo.cfg i have configured as > server.1 = XX.XX.XX.XX:65175:65173 > server.2 = XX.XX.XX.XX:65185:65183 > server.3 = XX.XX.XX.XX:65195:65193 > server.4 = XX.XX.XX.XX:65205:65203:observer > server.5 = XX.XX.XX.XX:65215:65213:observer > server.6 = XX.XX.XX.XX:65225:65223:observer > Like above I have configured 3 PARTICIPANTS and 3 OBSERVERS > in the cluster of 6 zookeepers > Steps to reproduce the defect > 1. Start all the 3 participant zookeeper > 2. Stop all the participant zookeeper > 3. Start zookeeper 1(Participant) > 4. Start zookeeper 2(Participant) > 5. Start zookeeper 4(Observer) > 6. Create a persistent node with external client and close it > 7. Stop the zookeeper 1(Participant neo quorum is unstable) > 8. Create a new client and try to find the node created b4 using exists api > (will fail since quorum not statisfied) > 9. Start the Zookeeper 1 (Participant stabilise the quorum) > Now check the observer using 4 letter word (Server.4) > linux-216:/home/amith/CI/source/install/zookeeper/zookeeper2/bin # echo stat > | netcat localhost 65200 > Zookeeper version: 3.3.2-1031432, built on 11/05/2010 05:32 GMT > Clients: > /127.0.0.1:46370[0](queued=0,recved=1,sent=0) > Latency min/avg/max: 0/0/0 > Received: 1 > Sent: 0 > Outstanding: 0 > Zxid: 0x100000003 > Mode: observer > Node count: 5 > check the participant 2 with 4 letter word > Latency min/avg/max: 22/48/83 > Received: 39 > Sent: 3 > Outstanding: 35 > Zxid: 0x100000003 > Mode: leader > Node count: 5 > linux-216:/home/amith/CI/source/install/zookeeper/zookeeper2/bin # > check the participant 1 with 4 letter word > linux-216:/home/amith/CI/source/install/zookeeper/zookeeper2/bin # echo stat > | netcat localhost 65170 > This ZooKeeper instance is not currently serving requests > We can see the participant1 logs filled with > 2011-11-08 15:49:51,360 - WARN > [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:65170:NIOServerCnxn@642] - Exception > causing close of session 0x0 due to java.io.IOException: ZooKeeperServer not > running > Problem here is participent1 is not responding / accepting any requests -- This message is automatically generated by JIRA.
