Jim Brennan commented on YARN-7677:
-----------------------------------
[~shaneku...@gmail.com], I am trying to repro locally. In my dev setup, it is
currently working, but I typically run with
mapreduce.application.framework.path and mapreduce.application.classpath
defined in my mapred-site.xml file, pointing to a tarball in my home dir in
hdfs.
If i remove those, I do get errors like these:
{noformat}
Error: Could not find or load main class
org.apache.hadoop.mapreduce.v2.app.MRAppMaster
Please check whether your etc/hadoop/mapred-site.xml contains the below
configuration:
<property>
<name>yarn.app.mapreduce.am.env</name>
<value>HADOOP_MAPRED_HOME=${full path of your hadoop distribution
directory}</value>
</property>
<property>
<name>mapreduce.map.env</name>
<value>HADOOP_MAPRED_HOME=${full path of your hadoop distribution
directory}</value>
</property>
<property>
<name>mapreduce.reduce.env</name>
<value>HADOOP_MAPRED_HOME=${full path of your hadoop distribution
directory}</value>
</property>
{noformat}
Is this what you are seeing? I don't think this behavior was different before
my change, but I'm going to revert it locally and double-check.

> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Eric Badger
> Assignee: Jim Brennan
> Priority: Major
> Fix For: 3.1.0, 3.0.1

> Attachments: YARN-7677.001.patch, YARN-7677.002.patch

> 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.
