Subject [jira] Commented: (HADOOP-3307) Archives in Hadoop.
Date Tue, 29 Apr 2008 19:08:55 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12593082#action_12593082

Doug Cutting commented on HADOOP-3307:
--------------------------------------

> We would need mounts to make it transparent and some storage in the filesystem to know
what we are supposed to do with the mounts.

Perhaps.  But we don't want to go there in this issue, right?

> I was trying to get rid of the implicit assumption. [ ... ]

The assumption that an archive directory name end with ".har"?  Is that what troubles you?

Here's another option: use percent-encoding to name the archive dir in the authority, e.g.,
har://hdfs:%2F%2Fhost:port%2Fdir%2Farchive/a/b.  This is harder to read, but otherwise elegant
and general.

Or yet another option: use the name of a file *within* the archive directory, like the index
or parts which will also presumably be fixed, not user-variable.  Then a path might look something
like har://hdfs-host:port/dir/archive/har.index/a/b, where "har.index" is hardwired.
