Zhankun Tang commented on YETUS-711:
------------------------------------
[~aw], sorry for the misleading "error output". I mean the unexpected string in
the modified unit test. There seems no code could generate the output string.
Actually, I've no idea of what happens.
Do you have any suggestion how can we root this issue? This code change is
actually a different parameter passed into "string.replace". And all related
code reference I've checked, cannot think why this happens.
> maven unit test result is different when running "mvn test
> -Dtest=TestContainerLaunch" under different directories

> Found this issue when YARN-7277 (on trunk). The patches consist of changes
> under both "hadoop-yarn-api" and "hadoop-yarn-server-nodemanager". In
> essence, the code changes are doing some string replacement. For instance, a
> constructed string
> "{{HADOOP_COMMON_HOME}}" will be transformed to "$HADOOP_COMMON_HOME". After
> the patch, the constructed string will be "{_{HADOOP_COMMON_HOME}_}" and
> still expected to be transformed to "$HADOOP_COMMON_HOME".
> The fact is that, when doing unit test, Yetus runs "mvn test
> -Dtest=TestContainerLaunch" under "hadoop-yarn-server-nodemanager" and failed
> with a weird output.
> I can reproduce the same error output with "mvn clean package -DskipTests
> -DskipShade" and "cd hadoop-yarn-server-nodemanager" and then "mvn test
> -Dtest=TestContainerLaunch".
> But when I run above mvn test command in parent direcotry "hadoop-yarn" or
> "hadoop-yarn-project", the unit test will success.
> I think the above issue is quite strange. So please help on this.
> And another thing weirder is that when I run "mvn clean test
> -DTestContainerLaunch" under nodemanager direcotry, the error output is
> different with Yetus error output.
