About “Leader Election”part of zookeeper recipes documention(
of my colleagues are confused on this: "Otherwise, watch for changes on
"ELECTION/guid-n_j", where j is the smallest sequence number such that j <
i and n_j is a znode in C;"
In my course, I tell them that in this using case， just watch the node
that only smaller than you, And the meaning of the expression here is
I think the document is error。
