Building an Impenetrable ZooKeeper Has code image
Kathleen Ting
Apache ZooKeeper is a project that provides reliable and timely coordination of processes. Given the many cluster resources leveraged by distributed ZooKeeper, it’s frequently the first to notice issues affecting cluster health, which explains its moniker: “The canary in the Hadoop coal mine.”

Come to this class and you will learn:
    •    How to configure ZooKeeper reliably
    •    How to monitor ZooKeeper closely
    •    How to resolve ZooKeeper errors efficiently

Culling from the diverse environments we’ve supported, we will share what it takes to set up an impenetrable ZooKeeper environment, what parts of your infrastructure specifically to monitor, and which ZooKeeper errors and alerts indicate something seriously amiss with your hardware, network or HBase configuration.
