Lingfeng Su created YARN-7062:
---------------------------------
Summary: yarn job args changed by
ContainerLaunch.expandEnvironment(), such as "{{" and "}}"
Key: YARN-7062
URL: https://issues.apache.org/jira/browse/YARN-7062
Project: Hadoop YARN
Issue Type: Improvement
Components: applications
Reporter: Lingfeng Su
Assignee: Lingfeng Su
Priority: Minor
I passed a json string like "{User: Billy, {Age: 18}}" to main method args,
when running spark jobs on yarn. It may exchange by
ContainerLaunch.expandEnvironment() to "{User: Billy, {Age: 18" ("}}" to "")
I found the final arg in launch_container.sh of yarn containers, as:
--arg '{User: Billy, {Age: 18'
{code:bash}
exec /bin/bash -c

{code}
We could make some improvements
