Zookeeper

Overview​

ZooKeeper is a distributed, open-source coordination service for distributed applications.

Integration Manager leverages ZooKeeper for Job Execution Mutex capabilities when executing across multiple engines, multiple workers, and/or distributed worker pools.

Integration Manager is compatible with Apache ZooKeeper 3.6.3 in Standalone Operation or Replicated Ensemble Deployments.

Quick Start Installation​

Prerequisite: Java 11

  1. Download Apache ZooKeeper 3.6.3: https://www.apache.org/dyn/closer.lua/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz
  2. Unzip to a Java-friendly path (no spaces), e.g. C:/ProgramData/Apache/zookeeper-3.6.3 (Windows), or /opt/Apache/zookeeper-3.6.3 (Linux)
  3. Create data directory at ../Apache/zookeeper-3.6.3/data.
  4. Rename zoo_sample.cfg to zoo.cfg in ../Apache/zookeeper-3.6.3/conf.
  5. In zoo.cfg, set:
    • Windows: dataDir=C:/ProgramData/Apache/zookeeper-3.6.3/data
    • Linux: dataDir=/opt/Apache/zookeeper-3.6.3/data
  6. Add a new system environment variable ZOOKEEPER_HOME:
    • Windows: ZOOKEEPER_HOME = C:/ProgramData/Apache/zookeeper-3.6.3
    • Linux: ZOOKEEPER_HOME = /opt/Apache/zookeeper-3.6.3
  7. Edit the system environment variable PATH by adding the entry: 
    %ZOOKEEPER_HOME%/bin
  8. Open a command prompt and type zkserver to verify your installation.

Integration Manager Configuration​

Integration Manager uses the "zookeeper" prefix properties in the application.properties file to connect to a ZooKeeper Standalone or Ensemble deployment.

note

Any change to application.properties requires a restart of the Integration Manager Service.

Here are some example properties to connect Integration Manager to a ZooKeeper deployment:

# ZooKeeper Connection Info
zookeeper.enabled=true
zookeeper.connection-string=10.0.1.101:2181,10.0.2.101:2181,10.0.3.101:2181 # comma separated list of zk ensemble IP(s) and port(s)
