Subject [jira] Commented: (HADOOP-6893) FileContext needs a method to test for existence of a file or directory.
Date Mon, 02 Aug 2010 05:38:16 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12894465#action_12894465
] 

Owen O'Malley commented on HADOOP-6893:
---------------------------------------

I see now that there is a Util method that checks exist, but it still uses getFileStatus and
catches the exception. There should be some way of asking an AbstractFileSystem whether a
name exists that doesn't throw an exception.

> FileContext is missing a method to ask if a file or directory exists. Currently the only
mechanism is to use getFileStatus, which throws an exception if the file doesn't exist, which
I don't think is an appropriate use of that method.
