我不断收到异常,因为Oozie在classpath中添加了错误版本的httpcore jar。我尝试了不同的选项,如
oozie.launcher.mapreduce.task.classpath.user.precedence
oozie.launcher.mapreduce.user.classpath.first
oozie.launcher.mapreduce.task.classpath.user.precedence完全没有响应,当我使用oozie.launcher.mapreduce.user.classpath.first时,应用程序甚至无法加载一个类。
在类路径中,我可以看到两个版本的http-core。
httpcore-4.4.1.jar
httpcore-4.2.4.jar
当应用程序以独立模式运行时,我没有得到该异常。
例外:

Oozie客户端构建版本:4.2.0.2.3.2.0-2950
感谢任何帮助。
答案 0 :(得分:3)
我们在HortonWorks发行版2.3.2 中遇到了这个令人讨厌的问题(对它们感到羞耻):
httpcore
和httpclient
CLASSPATH作为Hadoop客户端的一部分httpcore
和httpclient
捆绑在&#34; Oozie&#34; ShareLib httpcore
和httpclient
更新版本 user.classpath.first
适用于两者
ShareLibs所以它有50/50的机会为每个人获得正确的订单
JAR(整体上有25/75的机会)底线:我们必须
httpcore
和httpclient
来自&#34; Oozie&#34; ShareLib HDFS
dir(duh!)oozie.launcher.mapreduce.job.user.classpath.first
标志(即Hive操作,Hive2操作,以某种方式调用JDBC驱动程序的Shell操作等) Post-scriptum - Oozie服务器在内存中保存每个ShareLib中的JAR列表,以便在服务器运行时删除JAR将触发新作业中的错误。如果您不想停止Oozie服务器,那么&#34;正确的方式&#34;更新实时ShareLib是(a)在新的带时间戳的目录中创建新版本 [查看文档...] 和(b )告诉服务器使用oozie admin -sharelibupdate
答案 1 :(得分:0)
您希望使用本地版本的httpcore
JAR进行构建,但是您不希望它出现在您的类路径中,因为Hadoop将提供自己的版本。那么您应该使用provided
JAR的httpcore
范围:
<project>
...
<dependencies>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
<scope>provided</scope> <!-- this line is important -->
<version>4.4.1</version>
</dependency>
</dependencies>
</project>
来自provided
的{{3}}:
这很像compile,但表示您希望JDK或容器在运行时提供依赖。
