Class LocalOozieClientCoord

java.lang.Object

org.apache.oozie.client.OozieClient

org.apache.oozie.LocalOozieClientCoord

public class LocalOozieClientCoord
extends OozieClient

Client API to submit and manage Oozie coordinator jobs against an Oozie intance.

This class is thread safe.

Syntax for filter for the getJobsInfo(String) getJobsInfo(String, int, int) methods: [NAME=VALUE][;NAME=VALUE]*.

Valid filter names are:

• name: the coordinator application name from the coordinator definition.
• user: the user that submitted the job.
• group: the group for the job.
• status: the status of the job.

The query will do an AND among all the filter names. The query will do an OR among all the filter values for the same name. Multiple values must be specified as different name value pairs.
