Subject [jira] Updated: (HADOOP-4760) HDFS streams should not throw exceptions when closed twice
Date Tue, 10 Feb 2009 10:05:10 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4760?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Enis Soztutar updated HADOOP-4760:
----------------------------------

    Attachment: closehdfsstream_v2.patch

Incorporated Raghu's comments, now checkOpen() is called if closed is false. Also fixed the
DFSClient.close() method to not throw exception. 

The @Override's are pretty useful (espcecially when refactoring) and they are introduced intentionally
by my eclipse save actions. I am in favor of keeping them.

import statements are reordered and * are converted to actual classes again by save actions.
According to our guidelines, the import statements should only contain actual class references.
As in this case here, the import statements are constantly switched between actual class names
or * between patches. Maybe we should add checking for this to test-patch script.

instance, if the stream is a HDFS stream the {{loadResource(..)}} method fails with {{IOException}}
indicating that the stream has already been closed.
