----------------------------------
Summary: TestRouterWebServicesREST is corrupting STDOUT
Key: YARN-10161
URL: https://issues.apache.org/jira/browse/YARN-10161
Project: Hadoop YARN
Issue Type: Test
Components: yarn
Affects Versions: 2.10.0
Reporter: Jim Brennan
TestRouterWebServicesREST is creating processes that inherit stdin/stdout from
the current process, so the output from those jobs goes into the standard
output of mvn test.
Here's an example from a recent build:

[WARNING] Corrupted STDOUT by directly writing to native stream in forked JVM

It seems like these processes should be rerouting stdout/stderr to a file
instead of dumping it to the console.
