-------------------------------
Summary: Could not find or load main class
org.apache.tez.dag.app.DAGAppMaster
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

Container exited with a non-zero exit code 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.
