Subject [jira] [Resolved] (HADOOP-7840) Cleanup unnecessary exceptions thrown and unnecessary casts
Date Sat, 22 Sep 2012 14:31:07 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-7840?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Harsh J resolved HADOOP-7840.
-----------------------------

    Resolution: Invalid

If we remove those "throws IOException" bits out of the methods you've changed, won't we inadvertently
affect DistributedFileSystem that does Override these methods and makes use of the throws
specification? We'll be breaking API if am not wrong.

For example, I tried removing "throws IOException" from FileSystem and DistributedFileSystem
immediately complained at the overriden method cause it broke compatibility.

I'm closing this as Invalid, at this point, but please reopen if I got something wrong.
