[jira] [Updated] (HADOOP-8349) ViewFS doesn't work when the root of a file system is mounted

     [ https://issues.apache.org/jira/browse/HADOOP-8349?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aaron T. Myers updated HADOOP-8349:
-----------------------------------

    Attachment: HADOOP-8349.patch

Here's a patch which addresses the issue. The crux of the problem was two separate off-by-one errors in ChRootedFileSystem. Since to test this requires that we be able to mount and futz with files/directories at the root of the target file system, I put the test to exercise this in HDFS.

> Viewing files under a ViewFS mount which mounts the root of a file system shows trimmed paths. Trying to perform operations on files or directories under the root-mounted file system doesn't work. More info in the first comment of this JIRA.
