> Key: TEZ-3392
> URL: https://issues.apache.org/jira/browse/TEZ-3392
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.8.4
> Environment: CentOS release 6.8 (Final) x64bit
> Hadoop 2.7.2
> apache tez 0.8.4
> Reporter: amethystic
>
> Running Tez examples but ResourceManager showed it failed due to:
> Could not find or load main class org.apache.tez.dag.app.DAGAppMaster
> Sounds like there is an already-prebuilt .tar.gz
> file(apache-tez-0.8.4-bin.tar.gz) staring 0.8.4, so I used this file directly
> instead of compiling by myself and put it onto HDFS path: /apps/tez
> My tez-site.xml is:
> <?xml version="1.0" encoding="UTF-8"?>
> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
> <configuration>
> <property>
> <name>tez.lib.uris</name>
>
> <value>hdfs://localhost:8500/apps/tez/apache-tez-0.8.4-bin.tar.gz</value>
> </property>
> </configuration>
> mapreduce.framework.name was also set to yarn-tez in mapreduce-site.xml.
> All env variables were set in hadoop-env.sh:
> export TEZ_JARS=/mnt/disk/huxi/tez
> export TEZ_CONF_DIR=/mnt/disk/huxi/hadoop/etc/hadoop
> export
> HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/mnt/disk/huxi/tez/*:/mnt/disk/huxi/tez/lib/*:/mnt/disk/huxi/tez/conf/*
> When issuing command "bin/hadoop jar
> /mnt/disk/huxi/tez/tez-examples-0.8.4.jar orderedwordcount ./NOTICE.txt
> /out", RM showed the task was failed:
>
> Application application_1470107708886_0001 failed 2 times due to AM Container
> for appattempt_1470107708886_0001_000002 exited with exitCode: 1

> Failing this attempt. Failing the application.
> After checking the log, stederr complained that :
> Error: Could not find or load main class org.apache.tez.dag.app.DAGAppMaster
> Weird enough, tez-dag-0.8.4.jar should be in the classpath. So please be
> advice.
