Subject [jira] [Commented] (HDFS-2551) fuse-dfs's close() is asynchronous
Date Wed, 03 Oct 2012 22:13:08 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2551?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13468908#comment-13468908
] 

Todd Lipcon commented on HDFS-2551:
-----------------------------------

ah, I see. Then this seems like it might be a reasonable workaround. There's no way to do
our own reference counting? (ie we don't have any clue when an fd gets duped?)

> FUSE's "release" operation is called asynchronously when a file is closed from userspace.
This means that, if a program writes a file, closes it, and immediately re-opens it, it might
not succeed. We should figure out some workaround or trick to make close synchronous, if possible.
