Subject [jira] [Commented] (HADOOP-8014) ViewFileSystem does not correctly implement getDefaultBlockSize, getDefaultReplication, getContentSummary
Date Fri, 06 Apr 2012 16:47:23 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8014?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13248483#comment-13248483

John George commented on HADOOP-8014:
-------------------------------------

bq. In the new patch - {{Its spec and implementation is identical to {@link ViewFs}.}} not
sure what you mean here. Can you please add description on when this is used or what error
it conveys? Once you address that I am +1 for the patch, if the test failure is unrelated
to this.
Added a better description.
TestViewFsTrash seemed to fail in earlier builds as well (eg: [829|https://builds.apache.org/job/PreCommit-HADOOP-Build/829//testReport/],
[830|https://builds.apache.org/job/PreCommit-HADOOP-Build/830//testReport/]).

> {{ViewFileSystem}} incorrectly returns the {{FileSystem}} default values for {{getDefaultBlockSize()}}
and {{getDefaultReplication()}}.  This causes files to be created with incorrect values. 
The problem is that the current apis are insufficient for viewfs because the defaults depend
on the underlying mount point.  These methods need counterparts that accept a {{Path}} so
viewfs can resolve the mount point for a path.
