> Key: HDFS-4027
> URL: https://issues.apache.org/jira/browse/HDFS-4027
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.0.0-alpha

> I've seen jenkins failures (eg TestHDFSFileSystemContract) where
> DF#parseExecResult fails with an IOE "Expecting a line not the end of stream"
> due to what looks like a local storage failure. We should better log the
> output/exceptions from DF so we can see what the root cause was.
