Subject [jira] Commented: (HADOOP-3797) FUSE module chokes on directories with lots (10,000+ or so) files
Date Sun, 20 Jul 2008 06:41:31 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3797?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12615068#action_12615068

Craig Macdonald commented on HADOOP-3797:
-----------------------------------------

Pete,

Can you comment on how exactly fuse-dfs "chokes"? 

If I do an ls on a NFS folder with many files in it, it will likely also take some time to
return. Is the time to perform the ls comparable to a similar NFS mounted folder? Or does
fuse-dfs fail - you've marked it as a bug?

Craig

> For some reason, fuse is calling getattr for every file after doing a readdir. The readdir
supplies the same info so there's no reason for the getattr calls (that I can see) and it
does not do this for subdirectories.
> I don't know why it's doing this, so I sent an email to the fuse development list.
