Subject [jira] Commented: (HADOOP-6796) FileStatus allows null srcPath but crashes if that's done
Date Wed, 02 Jun 2010 05:56:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12874437#action_12874437
] 

Jakob Homan commented on HADOOP-6796:
-------------------------------------

bq. You could also modify Path to accept Path("") or Path(null) so that instead of throwing
an exception they silently convert to Path("/")

Nope - silent conversions are evil.  

The current patch  is probably the best way to go, although this new behavior needs to be
documented thoroughly.  The general rule of thumb with anything implementing writable is caveat
utilitor - let the user beware. Because of the write and readFields methods as well as the
default constructor, it's always best practice to verify the state of the instance you're
dealing with.

> FileStatus allows constructor invocation with a null srcPath but many methods like write,
readFields, compareTo, equals, and hashCode depend on this property.
