Subject [jira] [Commented] (HADOOP-9631) ViewFs should use underlying FileSystem's server side defaults
Date Tue, 18 Jun 2013 05:41:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9631?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13686409#comment-13686409

Lohit Vijayarenu commented on HADOOP-9631:

Taking a look at how ViewFs mountable is constructed, it looks there is no straightforward
way to get TargetFileSystem given mount point or path. I started with changing getServerDefaults
to accept Path. Now, create call would pass a Path which does not exists. So, we will have
to resolve the Path to mountpoint. I see that ViewFileSystem::resolve can fetch the mountpoint,
but not an easy way to fetch underlying FileSystem. '/' seem to always resolve to InteralViewOfDir
which does not have targetFileSytem. Any suggestions of easy way to fetch this?
