Subject [jira] Commented: (HADOOP-6900) FileSystem#listLocatedStatus should not throw generic RuntimeException to indicate error conditions
Date Thu, 05 Aug 2010 22:43:18 GMT

Hairong Kuang commented on HADOOP-6900:
---------------------------------------

Suresh, good idea! I appreciate your thoughts on this.

I will create a new Iterator interface that throws IOException on next() and hasNext().

I will make listFiles, listLocatedStatus, AND listStatus to return this new iterator iterface.
How does this sound to you?

> 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.
