--------------------------------------
Summary: container-executor error should include effective user id
Key: YARN-4065
URL: https://issues.apache.org/jira/browse/YARN-4065
Project: Hadoop YARN
Issue Type: Improvement
Components: yarn
Reporter: Casey Brotherton
Priority: Trivial
When container-executor fails to access it's config file, the following message
will be thrown:
{code}
org.apache.hadoop.yarn.server.nodemanager.LinuxContainerExecutor: Exit code
from container executor initialization is : 24
ExitCodeException exitCode=24: Invalid conf file provided :
/etc/hadoop/conf/container-executor.cfg
{code}
The real problem may be a change in the container-executor not running as set
uid root.
From:
https://hadoop.apache.org/docs/r2.6.0/hadoop-yarn/hadoop-yarn-site/SecureContainer.html
{quote}
The container-executor program must be owned by root and have the permission
set ---sr-s---.
{quote}
The error message could be improved by printing out the effective user id with
the error message, and possibly the executable trying to access the config file.
