Subject [jira] Commented: (HADOOP-6900) FileSystem#listLocatedStatus should not throw generic RuntimeException to indicate error conditions
Date Wed, 11 Aug 2010 18:59:17 GMT

Konstantin Shvachko commented on HADOOP-6900:
---------------------------------------------

Hairong. You changed the prototype of {{AbstractFileSystem.listStatusIterator(Path)}} but
did not change its overloaded version {{Hdfs.listStatusIterator(Path)}}. Could you please
fix it, as current build is broken as it is.

> HDFS-6870 introduced FileSystem#listLocatedStatus(), that returns an Iterator to iterate
through LocatedFileStatus for files under a directory or recursively under a sub-directory.
Iterator currently throws generic RuntimeException to indicate error conditions. API needs
to be changed to throw appropriate exceptions to indicate error conditions.
