Subject [jira] [Updated] (HADOOP-8349) ViewFS doesn't work when the root of a file system is mounted
Date Fri, 04 May 2012 00:06:56 GMT

     [ 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 an updated patch which makes all the same changes to the FileContext side of the house.
Indeed, the same two off-by-one errors were present in ChRootedFs as well.

bq. Why is it running a uri path through Path just to get the path again?

Because {{URI#getPath()}} returns a {{String}}, not a {{Path}} object. We probably could just
assign {{chRootPathPartString}} to {{uir.getPath()}}, but that might drop any mangling that
the {{Path}} constructor is doing.

> 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.
