Per Bergland commented on YARN-1340:
------------------------------------
prepareDirs should do:
new File(path).toURI().toURL() on the paths if the NM_LOCAL_DIR is supposed to
be URIs
> MiniYARNCluster generates wrong style directories in
> YarnConfiguration.NM_LOCAL_DIR, causes tests to fail if path contains space
> --------------------------------------------------------------------------------------------------------------------------------

> Key: YARN-1340
> URL: https://issues.apache.org/jira/browse/YARN-1340
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.0.6-alpha
> Environment: Mac OS X 10.8.5, CentOS 6.3
> Reporter: Per Bergland
>
> We found that our tests based on the ClusterMapReduceTestCase class failed
> when the jenkins job contained spaces and were able to reproduce the error by
> just renaming the project directory to contain a space character.
> The failure happens when validatePaths method in LocalDirsHandlerService
> tries to interpret the paths as URLs "new URL(dir)" and this fails.
> https://svn.apache.org/repos/asf/hadoop/common/tags/release-2.0.6-alpha/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/LocalDirsHandlerService.java
> The code in the MiniYARNCluster.prepareDirs method needs to be modified to
> create properly escaped file://-based URLs instead of raw file paths OR the
> receiving end in LocalDirsHandlerService needs to stop interpreting the
> directories as urls. Since MiniYARNCluster is a test class I suspect that the
> former needs to be done.
