A simple tool for browsing and modifying zookeeper trees.
On first run it will create a config file in your home directory .JZookeeperEdit where it will save details of servers you connect to if you click "Save Cluster Details"
This tool was written using Java 11 with OpenFX and Maven as its build tool. This means you will need the environment variable JAVA_HOME to point to a valid Java 11 Home.
Zookeeper comes with a nice little command line tool for exploration. However for scripting the metadata and the format can be a pain. This tool comes with a limited (but more customisable in terms of output) cli of its own. The main aim here was to make a zkCli that was a little more unix-tools friendly.
You can see the options by running java -jar JZookeeperEdit.jar -h.
Several notable features include:
- The ability to chain ls calls. For example to get all children of the children of the root one could run
java -jar JZookeeperEdit.jar -l -p -c localhost / | xargs java -jar JZookeeperEdit.jar -l -c localhostNaturally you can extend this via some grepping or awk commands or even asking questions like "do the children in one cluster have children in another". Note that if you wish to chain calls you will need to use the-pflag to have it print the full paths. - The ability to extract particular elements from metadata and a more unix tools friendly meta output i.e.:
java -jar JZookeeperEdit.jar -m -f getNumChildren -c localhost /Note that a full list of available accessors is available viajava -jar JZookeeperEdit.jar -a
mvn javafx:run
