Kazuho Fujii created HADOOP-12543:
-------------------------------------
Summary: Path#isRoot() returns true if the path is ".".
Key: HADOOP-12543
URL: https://issues.apache.org/jira/browse/HADOOP-12543
Project: Hadoop Common
Issue Type: Bug
Components: fs
Reporter: Kazuho Fujii
{{Path#isRoot()}} methods is expected to return true if and only if the path
represents the root of a file system. But, it returns true in the case where
the path is ".". This is because {{getParent()}} method returns null when the
path in URI is empty.
