> Key: HDFS-3682
> URL: https://issues.apache.org/jira/browse/HDFS-3682
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: test
> Affects Versions: 2.0.0-alpha
> Reporter: Eli Collins
> Assignee: Todd Lipcon
> Priority: Minor
> Labels: test-fail

>
> I've seen the occasional test failure due to the MiniDFSCluster init failing
> due to "java.io.IOException: Cannot remove data directory" for the
> target/test/data/dfs/data directory. We should improve the error handling
> here so we can better understand the failure, eg perhaps one of the tests
> that chmods a directory fails and causes this failure.
