Re: 3.3.2 -> 3.4.0 NodeExistsException when reading snapshot
Stefan,
 It mostly looks like
https://issues.apache.org/jira/browse/ZOOKEEPER-1319, but just to
confirm can you do this -

do a get on the same znode "/seq/y77mmizznsmdggqzx493-0030010980" on
each of the servers. You can just use the zkCli.sh to do that:

zkClish.sh -server hostname1 port1
get  /seq/y77mmizznsmdggqzx493-0030010980

similar for other hosts and post the results?

thanks
mahadev
