OozieClient (Apache Oozie Client 4.1.0-cdh5.12.1 API)

java.lang.Object
- org.apache.oozie.client.OozieClient

Direct Known Subclasses:

XOozieClient
```
public class OozieClient
extends Object
```
Client API to submit and manage Oozie workflow 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 workflow application name from the workflow 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.
