HDP on Linux – Installation Forum

Zookeeper failed to start after reboot

  • #14735

    Hi :

    I have a HDP1.2 cluster with 10 nodes, and have installed HDP1.2 successfully with my cluster 10 days ago. My cluster worked fine for theses days until yesterday.
    Unfortunately, after reboot my cluster yesterday, I found I can only started HDFS and MapRed, but zookeeper service. Totally,I have 3 zookeepers with name as host001,host002 and host003.
    zookeepers in host002, and host003 seemed to be successfully started, but Zookeeper in host001 failed to be restarted. I am confused. What’s wrong with me ? What’s the correct reboot procedure to HDP1.2 ?

    PS1. I restarted amberi-serever in host001 and restarted ambari-client in host002-host010.
    PS2.Because I can not find zookeeper log file in /var/log/hadoop/zookeeper, so I do not know what to do now.

    Thanks for any help.

    Hi Jeff,

    It looks like all that you may have missed is restarting the ambari-agent on host001. Ambari-agent needs to be started on all hosts that have any hadoop services running on them.



    Hi tedr:

    Thanks for your help.

    Actually I have manually restarted zookeeper on hosty001 by “sudo -u zookeeper /usr/lib/zookeeper/bin/ start /etc/zookeeper/conf/zoo.cfg”

    I will try your suggestion next time while I restart cluster again.

    Hi, Jeff

    One thing you can try is to try to stop zookeeper from ambari web UI and start them if you installed your cluster with Ambari.
