Subject [jira] Commented: (HADOOP-7032) Assert type constraints in the FileStatus constructor
Date Sat, 13 Nov 2010 09:46:14 GMT

Eli Collins commented on HADOOP-7032:
-------------------------------------

Yes core runs with assertions enabled.  Funny you mention it, I'm running HDFS-697 (enable
asserts) on trunk as we speak.

> A FileStatus may represent a file, directory or symlink.  This is indicated using the
isdir and symlink members, let's add an assert that validates the contstraints on these members
(eg a directory may not have the symlink member set).  We could also verify this by having
more than one constructor but we don't statically know the type of the file status when we
create it.
