Subject [jira] [Commented] (YARN-7677) Docker image cannot set HADOOP_CONF_DIR
Date Tue, 13 Feb 2018 17:26:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16362696#comment-16362696
] 

Jim Brennan commented on YARN-7677:
-----------------------------------

I believe these are intermittent failures:
{noformat}
ERROR] Failures: 
[ERROR]   TestContainerManager.testContainerUpgradeRollbackDueToFailure:880 The Rolled-back
process should be a different pid. Actual: 17405
[ERROR]   TestContainerSchedulerQueuing.testKillOpportunisticForGuaranteedContainer:547 expected:<SCHEDULED>
but was:<RUNNING>
{noformat}

The check-style issues are due to adding an 8th argument to writeLaunchEnv(), and ContainerLaunch.call()
going over 150 lines.  I can remove an empty line to address that, but I'm not sure it's worth
it?

Aside from those issues, I think this Jira is ready to review.

> Currently, {{HADOOP_CONF_DIR}} is being put into the task environment whether it's set
by the user or not. It completely bypasses the whitelist and so there is no way for a task
to not have {{HADOOP_CONF_DIR}} set. This causes problems in the Docker use case where Docker
containers will set up their own environment and have their own {{HADOOP_CONF_DIR}} preset
in the image itself.
