Alejandro Abdelnur commented on HADOOP-4536:
--------------------------------------------
In the {{run}} method, the line:
{code}
jc.set("mapred.local.dir", "build/test/mapred/local");
{code}
should be changed to:
{code}
jc.set("mapred.local.dir", System.getProperty("test.build.mapred",
"build/test/mapred/local"));
{code}
Thus preserving the current behavior but allowing to change it via a system
property.
> MiniRMCluster hardcodes 'mapred.local.dir' configuration to

> Key: HADOOP-4536
> URL: https://issues.apache.org/jira/browse/HADOOP-4536
> Project: Hadoop Core
> Issue Type: Bug
> Components: test
> Environment: all
> Reporter: Alejandro Abdelnur
> Priority: Minor
>
> The {{mapred.local.dir}} configuration property for the {{MiniMRCluster}} is
> forced to {{build/test/mapred/local}}
> This is inconvenient in different situations. For example:
> * When running multiple tests using {{MiniMRCluster}} is not possible to see
> the end state of the dir for a particular test
> * When using {{MiniMRCluster}} in another build system (i.e. Maven) that uses
> a different output directory (target instead build)
