Http://zhangrenhua.com Blog has moved With the exception information, you can guess that the configuration was not read when the task was executed, so the default 0.0.0.0:8030 address was used. In order to verify whether this is the cause, we can modify the log level of log4j in the oozie/conf directory for debugging.Then, by viewing and tracking the source code of Hadoop, the correctness of the conjecture is verified, because
DescriptionTasks performed in Hadoop sometimes require multiple map/reduce jobs to be connected together in order to achieve the goal. In the Hadoop ecosystem,Oozie allows us to combine multiple map/reduce jobs into a single logical unit of work, To accomplish larger tasks. PrincipleOozie is a java Web application that runs in the Java servlet container- the Tomcat --in, and use the database to store the following:Workflow definitionCurrently running

Original link: http://blog.ywheel.cn/post/2016/06/12/hive_in_oozie_workflow/ By building and maintaining big data platforms in the company and providing it to other data analysts, Hive is the most (almost unique) service that non-programmers use. Of course, in daily data processing, in order to simplify the coding effort and use the results accumulated by the data analyst, we can use or simply modify the HQL scripts they provide for data processing, and dispatch hive jobs using

High-availability Hadoop platform-Oozie Workflow1. Overview When developing and using Hadoop-related applications, we can directly use Crontab to schedule related applications without complicated services and few tasks. Today, we will introduce the system for unified management of various scheduling tasks. The following is the content directory shared today: Content Oozie Server Preview Let's start tod

Pan introduces the pros and cons of both.HUE Development language: Python Pros: Hue is a WEB application that interacts with Apache Hadoop. An open-source Apache Hadoop UI. We've already used hue in our production environment, and Hue has a great advantage in managing hbase/pig/hive, and it comes with a Oozie app for creating and monitoring
About the execution conditions of input-events and Done-flag workflows for OozieWhen a workflow specified by coordinator has entered the Execution time window, Oozie first checks that all input-events have "occurred" (satisfied), and the check is mainly divided into two aspects: Does the specified file or folder already exist? If Done-flag is specified, check if the Done-flag file exists The workflow will enter the runing state only
First, introduceOozie is a Hadoop-based workflow Scheduler that can submit different types of jobs programmatically through the Oozie Client, such as mapreduce jobs and spark jobs to the underlying computing platform, such as Cloudera Hadoop.Quartz is an open-source scheduling software that provides a variety of triggers and listeners for scheduling execution of tasksThe following uses Quartz + Oozie to sub
/hdp/current/hive-webhcat/share/hcatalog will be ignored. This obviously looks weird, in fact hive can only read a hive_aux_jars_path, which is the main reason for the weird code above. So, it's a good idea that we can place our shared jar packages in one place, and then create a corresponding soft connection under/usr/hdp/current/hive-webhcat/share/hcatalog, for example, We put the jar uniformly under the/usr/lib/share-lib and then set up the soft connection: -u-s /usr/lib/share-lib/elasticsear
