Description

This issue was found when verifying submarine in Hadoop 3.2.0 RC1 planning. The reproduce steps are:

1. Init a new HDFS and YARN (LinuxContainerExecutor and Docker enabled)
2. Before run any other yarn service job, use yarn user to submit a submarine job

The job will fail with below error:

 

LogType:serviceam-err.txt

LogLength:86
LogContents:
Error: Could not find or load main class org.apache.hadoop.yarn.service.ServiceMaster
End of LogType:serviceam-err.txt

This seems because the dependencies are not ready as the service client reported:

2019-01-10 21:50:47,380 WARN client.ServiceClient: Property yarn.service.framework.path has a value /yarn-services/3.2.0/service-dep.tar.gz, but is not a valid file
2019-01-10 21:50:47,381 INFO client.ServiceClient: Uploading all dependency jars to HDFS. For faster submission of apps, set config property yarn.service.framework.path to the dependency tarball location. Dependency tarball can be uploaded to any HDFS path directly or by using command: yarn app -enableFastLaunch [<Destination Folder>]

 

When this error happens, I found that there is no “/yarn-services” directory created in HDFS.

But after I run “yarn app -launch my-sleeper sleeper”, the “/yarn-services” created in HDFS and then the submarine job can run successfully.

yarn@master0-VirtualBox:~/apache-hadoop-install-dir/hadoop-dev-workspace$ hdfs dfs -ls /yarn-services/3.2.0/*
-rwxr-xr-x 1 yarn supergroup 93596476 2019-01-11 08:23 /yarn-services/3.2.0/service-dep.tar.gz

It seems an issue of yarn service in 3.2.0 RC1 and I files this Jira to track it.

 

And verified that trunk branch doesn't have this issue.
