助闲她们干完一些惊夷的掠予使命先,而且熟悉了一个地天会头级头子——吴梓穆(Woozie)【一般皆喊他吴子。】但果替一些缘 …

1
With job properties in place, a command presented at Listing 4 can be used to run an Oozie workflow. 有了作业属性,我们就可以使用代码4中的命令来运行Oozie工作流。
2
Externalizing java class execution creates additional network traffic for synchronizing this execution with Oozie server. 在外部执行java类导致了额外的网络传输,用于与Oozie服务器同步这些执行结果。
3
This can be useful when Oozie worklows are either part of a specific application or a larger enterprise process. 当Oozie工作流是特定的应用程序或者大型企业过程的一部分,这就会很有用。
4
Once a workflow is deployed, an Oozie provides a command line utility [5] can be used to submit, start and manipulate a workflow. 完成了工作流的部署之后,我们可以使用Oozie提供的命令行工具[5],它可以用于提交、启动和操作工作流。
5
We also described deployment and configuration of workflow for Oozie and tools for starting, stoping and monitoring Oozie workflows. 我们还描述了针对Oozie的工作流的部署和配置,以及用来启动、停止和监控Oozie工作流的工具。
6
Oozie coordinator support creation of such data Application pipelines. Oozie协调程序支持创建这样的数据应用管道。
7
An Oozie console (Figure 2) can be used to watch the progress and results of workflow execution. 我们可以使用Oozie控制台(图2)来观察工作流执行的进程和结果。
8
Custom action nodes allow to extend Oozie' language with additional actions (verbs). 自定义的动作节点让我们可以使用附加的动作(动词)来扩展Oozie的语言。
9
In the next article we will look at a more complex example, allowing us to discuss more Oozie features. 在下一篇文章中,我们会看到更复杂的例子,让我们可以更进一步讨论Oozie的特性。
10
WorkflowAction provides Oozie' definition of the current action. 而WorkflowAction则提供了Oozie对当前动作的定义。
11
Here, first workflow client is initialized with Oozie server URL. 在此,我们首先使用Oozie服务器URL对工作流客户端进行初始化。
12
Oozie guarantees that both actions will be submitted to Job tracker in parallel. Oozie确保两个动作会并行地提交给作业跟踪程序。
13
The Oozie Coordinator system allows the user to define workflow execution schedules based on these parameters. Oozie协调系统(Coordinatorsystem)让用户可以基于这些参数来定义工作流执行计划。
14
They have also released Oozie, a workflow engine for Hadoop, which has become the de-facto ETL standard at Yahoo. 他们还发布了Oozie,一个Hadoop的工作流引擎,这已在雅虎成为事实上的ETL标准。
15
See this link for Oozie installation. 请参看Oozie安装的链接。
16
In this article we have shown how to extend Oozie by creating custom action executors. 在这篇文章中,我们展示了如何通过创建自定义的动作执行器来扩展Oozie。
17
In our previous articles [1, 2] we described Oozie workflow server and presented several workflow examples. 在前面的两篇文章中[1,2],我们描述了Oozie工作流服务器,并且展示了几个工作流的示例。
18
This is done via a callback from the action or Oozie polling for the action status. 这是通过动作的回调或者Oozie针对动作状态的polling操作完成的。
19
In this article we will introduce Oozie and some of the ways it can be used. 本文中,我们会向你介绍Oozie以及使用它的一些方式。
20
Check method, which is used by Oozie to check action's status. 还有Check方法,Oozie会使用它来检查动作的状态。
