Subject RE: Transaction log: /logs/jhe/nc/apps/zookeeper/version-2/log.1400470027 has invalid magic number 0 != 1514884167

Hi Suman,

This should be related to hostname. You have used below

server.1=host1:3888:4888
server.2=host2:3888:4888
server.3=host3:3888:4888

try to use actual hostname (or IP address preferable). I am using following in my Zookeeper
and it is working fine.

server.1=10.20.5.129:2888:3888
server.2=10.20.5.194:2888:3888
server.3=10.20.5.195:2888:3888

Thanks,
Dilip Kumar

maxSessionTimeout=100000

server.1=host1:3888:4888
server.2=host2:3888:4888
server.3=host3:3888:4888


autopurge.snapRetainCount=3
autopurge.purgeInterval=1


Not sure what went wrong.  Any help is greatly appreciated.
