Subject [jira] [Updated] (HADOOP-9783) Fix OS detection for RawLocalFileSystem#getFileLinkStatus fallback path
Date Sun, 28 Jul 2013 20:21:48 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-9783?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Wang updated HADOOP-9783:
--------------------------------

    Attachment: hadoop-9783-1.patch

Patch attached. I made RLFS do positive rather than negative detection when determining whether
to use the new and improved code path.

Also took the opportunity to clean up the OS detection code in {{Shell}}, since we were doing
it twice.

> HADOOP-9652 calls out to {{stat(1)}} on supported platforms to get additional file metadata
and handle symlinks. The old, incorrect fallback path was left in for unsupported platforms.
However, the fallback is currently only in place for Windows; let's make it for any unsupported
platform (e.g. Mac).
