Simple CLI for Zookeeper
Why do we need another CLI for Zookeeper you ask?
I was bitten by the fact that the CLI that ships with Zookeeper, zkCli.sh is jsut one character different then the one that ships with Solr, zkcli.sh. Several hours of debugging later, I decided to write my own! I wanted to use the same commands I use in Unix, ls, cat, rm, du etc to work with data in Zookeeper.
There isn't a good one out there that is just based on Java, you need Go or Python or Scala as dependencies. I wanted to build a simple one that would allow the basic Unix style operators to work with Zookeeper.
The original version of this was based on the Solr client, and then I ported it to Curator.
List out nodes:
java -jar jackhanna.jar localhost:2181 ls /environment
java -jar jackhanna.jar localhost:2181 ls --zkPath=/environment
View the contents of a node:
java -jar jackhanna.jar localhost:2181 cat /environment/somevalue
java -jar jackhanna.jar localhost:2181 cat --zkPath=/environment/somevalue
List out the disk usage in Zookeeper:
java -jar jackhanna.jar localhost:2181 du /environment
java -jar jackhanna.jar localhost:2181 du --zkPath=/environment
Delete nodes in Zookeeper:
java -jar jackhanna.jar localhost:2181 rm /environment/properties
java -jar jackhanna.jar localhost:2181 rm --zkPath=/environment/properties
Put a single file into Zookeeper:
java -jar jackhanna.jar localhost:2181 putfile --zkFile /configs/ecommerce/rules.txt --file ./src/main/resources/sample_rules.txt
or to put a single file into a directory:
java -jar jackhanna.jar localhost:2181 put --zkPath /environment/config/log4j.xml --path ./src/main/resources/log4j.xml
Put a directory of files into Zookeeper:
java -jar jackhanna.jar localhost:2181 put --zkPath /environment/configs/resources --path ./src/main/resources
Get a single file from Zookeeper:
java -jar jackhanna.jar localhost:2181 get --zkPath /environment/config/log4j.xml --path /tmp
Get a directory of files from Zookeeper:
java -jar jackhanna.jar localhost:2181 get --zkPath /environment/configs/resources --path /tmp
There should be a brew install jackhanna but I haven't figured that out! For now you need to check the code out and do:
mvn install
cp ./bin/jackhanna /usr/local/bin
jackhanna --help
