Mike Drob commented on HBASE-18285:
-----------------------------------
I'm not sure what changed, but in my environment this now outputs
{noformat}
[WARNING] Corrupted stdin stream in forked JVM 1. See the dump file
/Users/mdrob/IdeaProjects/hbase/hbase-spark-it/target/failsafe-reports/2017-07-07T00-07-38_980-jvmRun1.dumpstream
{noformat}
which is both better and worse
> Failsafe ITs very noisy output to stdout

> Key: HBASE-18285
> URL: https://issues.apache.org/jira/browse/HBASE-18285
> Project: HBase
> Issue Type: Bug
> Components: integration tests
> Reporter: Mike Drob
>
> Way back in HBASE-14819 our Stack added some flags to our failsafe plugin
> runs to print more debugging information. This information is very useful,
> but should not be going to the console when we run ITs.
> The culprit flags are
> {{-XX:+PrintCommandLineFlags -XX:+PrintFlagsFinal -XX:+PrintGC}}
> If we want to have this information available, then we should send it off to
> a file.
