Chris Nauroth created YARN-1395:
-----------------------------------
Summary: Distributed shell application master launched with debug
flag can hang waiting for external ls process.
Key: YARN-1395
URL: https://issues.apache.org/jira/browse/YARN-1395
Project: Hadoop YARN
Issue Type: Bug
Components: applications/distributed-shell
Affects Versions: 2.2.0, 3.0.0
Reporter: Chris Nauroth
Assignee: Chris Nauroth
Distributed shell launched with the debug flag will run
{{ApplicationMaster#dumpOutDebugInfo}}. This method launches an external
process to run ls and print the contents of the current working directory.
We've seen that this can cause the application master to hang on
{{Process#waitFor}}.
