Livy Manager

Build Status

Abstract

Livy Manager is a Web UI for managing Apache Livy sessions.

Issues Livy Manager Tackles with

  • It is difficult for non-developer Livy users to monitor or kill their Livy sessions and Spark applications.
    • They have to use an HTTP client tool like curl to call the Livy REST APIs.
    • Additionally, they have to manipulate machines on which a Kerberos client is installed if the Livy service is Kerberized.
    • In some services which use Livy, there's no way to kill a Livy session while a Spark application is running, so non-developer users cannot stop their Spark applications by themselves when they submitted a heavy and long running application accidentally.

Solutions Livy Manager provides

  • Non-developer Livy users can see and kill their Livy sessions.
  • Optional LDAP authentication and authorization feature is included.
    • Admin users can see and kill all of the Livy sessions.
    • Non-admin users can see and kill only their Livy sessions.
    • This feature works well with Zeppelin with LDAP authentication and the Livy interpreter.
