via zkCli.sh you can easily save a string as a value using the create
command.
create /testdir "this is a string"
As far as loading a file into a zNode, it's just a matter of reading the
file into an array of bytes and then creating the zNode with that array of
bytes. I haven't used the native zookeeper client, but it's simple enough
with Apache Curator.
CuratorFramework curator = ... //Initialise your client
byte[] fileContents = readFileContent();
curator.create().forPath("/testdir", fileContents);
To read the data out
byte[] fileContents = curator.getData().forPath("/testdir");
cheers
