Ted Dunning commented on ZOOKEEPER-556:

In the following exchange, a new Zookeeper user lost several days wrestling 
with this issue.  Henry spotted the problem.  I didn't.  Patrick didn't.

With a prominent error message, the user would have found this in 5 minutes.

yeah - thought this was it: you've missed the forward slash on
home/mark/zookeeper (this turned up on your exception message).

> server.1= hermes:2888:3888

> It would be nice if the startup noticed directories without a leading slash 
> in the config file.  That is worth a warning.
> Moreover, if that directory exists looking from root, but not looking from 
> the current directory, a very serious warning is in order.
