Ahmed Radwan commented on MAPREDUCE-3736:
-----------------------------------------
I have checked for fs.default.name property and I didn't find it in any of
*-default.xml.
In previous hadoop versions, it usually exists in core-default.xml:
<property>
<name>fs.default.name</name>
<value>file:///</value>
</property>
I'll create a patch to set this property in core-default.xml and test if this
solves the problem.
> Variable substitution depth too large for fs.default.name causes jobs to fail

> Key: MAPREDUCE-3736
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3736
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.1
> Reporter: Eli Collins
> Assignee: Ahmed Radwan
> Priority: Blocker

> I'm seeing the same failure as MAPREDUCE-3462 in downstream projects running
> against a recent build of branch-23. MR-3462 modified the tests rather than
> fixing the framework. In that jira Ravi mentioned "I'm still ignorant of the
> change which made the tests start to fail. I should probably understand
> better the reasons for that change before proposing a more generalized fix."
> Let's figure out the general fix (rather than require all projects to set
> mapreduce.job.hdfs-servers in their conf we should fix this in the
> framework). Perhaps we should not default this config to "$fs.default.name"?
