hadoop - Oozie 和 Job History Server 配置问题

Question

问题

我正在尝试安装伪分布式 CDH在不使用 CDM 的情况下。一切都通过控制台“工作”。但是，我一开始使用 Hue，就在尝试使用 Pig 时收到错误消息。

Hue 中显示的错误是:

JA017: Could not lookup launched hadoop Job ID [job_local2125047777_0001] which was associated with action [0000000-160112011607704-oozie-oozi-W@pig]. Failing this action!

我认为这是一个错误，是由于连接 Pig 与作业历史服务器的 Oozie 工作流问题导致的沟通不畅所致。

在此之前，我无法从 Hue 使用 Hive，因为 Oozie 很难在 HDFS 上安装 Oozie 的 sharelib。我通过在 /etc/hadoop/conf/core-site.xml 之间创建符号链接(symbolic link)解决了这个问题和 /etc/oozie/conf/hadoop-conf/core-site.xml .如此处所建议:Apache Oozie failed loading ShareLib

脚本信息

我编写的用于将 CDH 安装到 Scientific Linux 7 上的配置脚本可在此处获得:https://github.com/coatless/stat490uiuc/blob/master/install_scripts/cdh_build.sh

具体来说，我正在尝试从 pig 脚本中获取结果:

data = LOAD '/user/hue/pig/examples/data/midsummer.txt' as (text:CHARARRAY);

upper_case = FOREACH data GENERATE org.apache.pig.piggybank.evaluation.string.UPPER(text);

STORE upper_case INTO '$output' ;

尝试的解决方案

通过谷歌搜索，我发现了以下解决方案，这些解决方案在实现后并未奏效。

• JA017: Could not lookup launched hadoop Job ID

建议运行以下命令:

sudo -u hdfs hadoop fs -mkdir -p /user/history
sudo -u hdfs hadoop fs -chmod -R 1777 /user/history
sudo -u hdfs hadoop fs -chown mapred:hadoop /user/history

重新启动资源和节点管理器、HDFS 和历史服务器无济于事。

在线程中，有另一个用户建议在job.properties 中设置一个属性。指定了 user.name=mapred .但是，我找不到任何对 Hue 作业的 job.properties 的引用。

• Oozie logs report Unknown hadoop job and history server UI not populated

这篇文章建议在 mapred-site.xml 中为历史服务器声明固定路径文件:

<property>
  <name>mapreduce.jobhistory.done-dir</name>
  <value>/user/history/done</value>
</property>
<property>
   <name>mapreduce.jobhistory.intermediate-done-dir</name>
   <value>/user/history/done_intermediate</value>
</property>

这也没有用。

• JA017: Unknown hadoop job

表示问题可能与权限问题有关，但是，用户没有提供有关如何解决问题的具体信息。

如有任何帮助，我们将不胜感激。

Answer 1

您应该使用 HUE 文件浏览器仔细检查/user/history 的所有目录和子目录的所有权限是否正确。

在我的例子中，所有用户都拥有对/user/history 的所有子文件夹的权限，但是 HUE 文件浏览器告诉我“/user/history”目录本身具有以下权限集:

Name        User     Group     Permissions
history     mapred   hadoop    drwxrwx--- 

当使用与 mapred 不同的用户时，这会导致错误。以下命令有帮助:

sudo -u hdfs hadoop fs -chmod 777 /user/history
