INode.getPathComponents throws NPE when given a non-absolute path
-----------------------------------------------------------------
Key: HADOOP-5700
URL: https://issues.apache.org/jira/browse/HADOOP-5700
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Minor
Attachments: HADOOP-5700.txt
If you pass a path that doesn't start with '/' to INode.getPathComponents, it
throws a NullPointerException. Instead it should throw IllegalArgumentException
to make it clear that absolute paths are required in this code.
The attached patch fixes this, clarifies, the javadoc, and adds a test case.
