Oozie workflow: Hive table not found but it does exist

由 流过昼夜 提交于 2019-12-21 02:34:53
问题 I got a oozie workflow, running on a CDH4 cluster of 4 machines (one master-for-everything, three "dumb" workers). The hive metastore runs on the master using mysql (driver is present), the oozie server also runs on the master using mysql, too. Using the web interface I can import and query hive as expected, but when I do the same queries within an oozie workflow it fails. Even the addition of the "IF EXISTS" leads to the error below. I tried to add the connection information as properties to

Oozie > Java action > why property oozie.launcher.mapred.child.java.opts does not work

问题 I am working on Oozie with a Java action. The Java action should use Java option -Xmx15g. Accordingly I set the property oozie.mapreduce.map.memory.mb to 25600 (25G) in case some extra memory is needed. After this simple setting, I ran the Oozie job, then there was of course OutofMemory (heap out of space) error during Java runtime. So I set oozie.launcher.mapred.child.java.opts as -Xmx15g accordingly in the property node of the Java action based on the link: http://downright-amazed.blogspot

Oozie shell action memory limit

问题 We have an oozie workflow with a shell action that needs more memory than what a map task is given by Yarn by default. How can we give it more memory? We have tried adding the following configuration to the action: <configuration> <property> <name>mapreduce.map.memory.mb</name> <value>6144</value> <!-- for example --> </property> </configuration> We have both set this as an inline (in the workflow.xml) configuration and as a jobXml. Neither has had any effect. 回答1: We found the answer: A

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> jopen 4年前发布 | 67K 次阅读 分布式/云计算/大数据 Apache Falcon Apache Falcon 是一个面向Hadoop的、新的数据处理和管理平台，设计用于数据移动、数据管道协调、生命周期管理和数据发现。它使终端用户可以快速地将他们的数据及其相关的处理和管理任务“上载（onboard）”到Hadoop集群。 Apache Falcon解决了大数据领域中一个非常重要和关键的问题。升级为顶级项目是该项目的一个重大进展。Apache Falcon有一个完善的路线图，可以减少应用程序开发和管理人员编写和管理复杂数据管理和处理应用程序的痛苦。 用户会发现，在Apache Falcon中，“基础设施端点（infrastructure endpoint）”、数据集（也称 Feed ）、处理规则均是声明式的。这种声明式配置显式定义了实体之间的依赖关系。这也是该平台的一个特点，它本身只维护依赖关系，而并不做任何繁重的工作。所有的功能和工作流状态管理需求都委托给工作流调度程序来完成 下面是Falcon的架构图： 从上图可以看出，Apache Falcon： 在Hadoop环境中各种数据和“处理元素（processing element）”之间建立了联系； 可以与Hive/HCatalog集成；
