Oozie 示例 map reduce 作业失败并出现 java.lang.NoSuchFieldError: HADOOP_CLASSPATH

Question

我在 hadoop 2.7.3 中安装了 oozie 4.3.0。 oozie 和 hadoop 服务已启动并正在运行。我尝试执行 oozie 分发附带的示例 map reduce 作业，当我检查作业日志时，它包含这些错误。

我在 google 中搜索了每个链接，但所提出的解决方法/解决方案都没有奏效。任何人都知道为什么会发生此错误。

我可以毫无问题地运行 map reduce 作业，并且我可以在 shell 提示符下使用“hadoop classpath”命令查看类路径详细信息。

我的 job.properties 文件

nameNode=hdfs://localhost:54310
jobTracker=localhost:8032
queueName=default
examplesRoot=examples

oozie.use.system.libpath=true

oozie.wf.application.path=${nameNode}/user/${user.name}/${examplesRoot}apps/map-reduce/workflow.xml
outputDir=map-reduce

并且 workflow.xml 没有变化，只是标准文件随 oozie 分发而来。

oozie-site.xml 配置文件是

    <configuration>

    <!--
        Refer to the oozie-default.xml file for the complete list of
        Oozie configuration properties and their default values.

            used when there is no exact match for an authority. The HADOOP_CONF_DIR contains
            the relevant Hadoop *-site.xml files. If the path is relative is looked within

以及用来运行的命令

$ bin/oozie job -oozie http://localhost:11000/oozie -config /srv/oozie-4.3.0/distro/target/oozie-4.3.0-distro/oozie-4.3.0/examples/apps/map-reduce/job.properties -run

$ bin/oozie job -oozie http://localhost:11000/oozie -log  0000003-161218192921381-oozie-hado-W

Answer 1

我遇到了同样的问题。经过几次搜索，我找到了来源。即使使用选项“-Dhadoop.version=2.7.3”指定 Hadoop 2.7.3，oozie 编译也会生成 Hadoop 2.6.0 jar。

请执行以下操作：

• 解压 oozie.war（在新目录中执行此部分）

  jar -xvf oozie.war

• 删除 oozie.war/WEB-INF/lib 中的所有 Hadoop jar（我对 Hive jar 做了同样的操作）。就我而言，我为 Hadoop 2.7.3 编译了 Oozie，但 Hadoop 2.6.0 jar 位于目录中。

  rm -f oozie.war/WEB-INF/lib/hadoop-*.jar rm -f oozie.war/WEB-INF/lib/hive-*.jar

• 新建一个oozie.war（你必须在oozie.war目录下）

  jar -cvf oozie.war ./*

• 使用 prepare-war 为 oozie 重新生成 oozie.war 二进制文件

  oozie-setup.sh prepare-war

• 错误不再可见

注意：您必须在 libext 目录中复制几个 Hadoop 和 Hive jar。我的 libext 目录如下所示：

`activation-1.1.jar,apacheds-i18n-2.0.0-M15.jar,apacheds-kerberos-codec-2.0.0-M15.jar,api-asn1-api-1.0.0-M20.jar,api-util-1.0.0-M20.jar,avro-1.7.4.jar,commons-beanutils-core-1.8.0.jar,commons-cli-1.2.jar,commons-codec-1.4.jar,commons-collections-3.2.2.jar,commons-compress-1.4.1.jar,commons-configuration-1.6.jar,commons-digester-1.8.jar,commons-httpclient-3.1.jar,commons-io-2.4.jar,commons-lang-2.6.jar,commons-logging-1.1.3.jar,commons-math3-3.1.1.jar,commons-net-3.1.jar,curator-client-2.7.1.jar,curator-framework-2.7.1.jar,curator-recipes-2.7.1.jar,ext-2.2.zip,gson-2.2.4.jar,guava-11.0.2.jar,hadoop-annotations-2.7.3.jar,hadoop-auth-2.7.3.jar,hadoop-common-2.7.3.jar,hadoop-hdfs-2.7.3.jar,hadoop-mapreduce-client-app-2.7.3.jar,hadoop-mapreduce-client-common-2.7.3.jar,hadoop-mapreduce-client-core-2.7.3.jar,hadoop-mapreduce-client-hs-2.7.3.jar,hadoop-mapreduce-client-jobclient-2.7.3.jar,hadoop-mapreduce-client-shuffle-2.7.3.jar,hadoop-yarn-api-2.7.3.jar,hadoop-yarn-client-2.7.3.jar,hadoop-yarn-common-2.7.3.jar,hadoop-yarn-server-applicationhistoryservice-2.7.3.jar,hadoop-yarn-server-common-2.7.3.jar,hadoop-yarn-server-resourcemanager-2.7.3.jar,hadoop-yarn-server-web-proxy-2.7.3.jar,hive-ant-2.1.0.jar,hive-common-2.1.0.jar,hive-exec-2.1.0.jar,hive-hcatalog-core-2.1.0.jar,hive-jdbc-2.1.0.jar,hive-metastore-2.1.0.jar,hive-serde-2.1.0.jar,hive-service-2.1.0.jar,hive-shims-0.23-2.1.0.jar,hive-shims-0.23.jar,hive-shims-2.1.0.jar,hive-shims-common-2.1.0.jar,hive-webhcat-java-client-2.1.0.jar,htrace-core-3.1.0-incubating.jar,httpclient-4.2.5.jar,httpcore-4.2.5.jar,jackson-core-asl-1.9.13.jar,jackson-jaxrs-1.9.13.jar,jackson-mapper-asl-1.9.13.jar,jackson-xc-1.9.13.jar,jaxb-api-2.2.2.jar,jaxb-impl-2.2.3-1.jar,jersey-client-1.9.jar,jersey-core-1.9.jar,jetty-6.1.26.jar,jetty-util-6.1.26.jar,jsr305-3.0.0.jar,leveldbjni-all-1.8.jar,libfb303-0.9.3.jar,log4j-1.2.17.jar,mysql-connector-java-5.1.25-bin.jar,netty-3.6.2.Final.jar,paranamer-2.3.jar,protobuf-java-2.5.0.jar,servlet-api-2.5.jar,slf4j-api-1.7.10.jar,slf4j-log4j12-1.7.10.jar,snappy-java-1.0.4.1.jar,stax-api-1.0-2.jar,xercesImpl-2.9.1.jar,xml-apis-1.3.04.jar,xmlenc-0.52.jar,xz-1.0.jar,zookeeper-3.4.6.jar`

当你做“准备战争”时，libext 内容被复制到 oozie-server/webapps/oozie/WEB-INF/lib/

Answer 2

转到 ozzie 服务器的 lib 目录

cd $OOZIE_HOME/oozie-server/webapps/oozie/WEB-INF/lib

列出 hadoop jar ls -l hadoop*.jar

所有列出的 jars 应该是相同的版本，并且应该与你安装的 hadoop 版本匹配，删除任何不同版本的 jars 并重新启动 oozie
