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.
