Import Yaml into ZooKeeper

This is an example of a yaml file to import

dump.yml (example)

---
organizations:
  departments:
    office[0]:
      employee[0]:
        email: "tom@mail.com"
        name: "Tom"
      employee[1]:
        name: "James"
      employee[2]:
        name: "Mark"
      area: "marketing"
    office[1]:
      employee[0]:
        name: "Steve"
      employee[1]:
        name: "Richard"
      area: "distribution"

command

We could import that yaml file using this command

zookeeperdump.groovy -c /config/application < dump.yml

Export Yaml from ZooKeeper

command

We could use this similar command for exporting.

zookeeperdump.groovy -x /config/application > dump.yml
