Subject [jira] Created: (HADOOP-2067) multiple close() failing in Hadoop 0.14

multiple close() failing in Hadoop 0.14
---------------------------------------

                 Key: HADOOP-2067
                 URL: https://issues.apache.org/jira/browse/HADOOP-2067
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
            Reporter: lohit vijayarenu


It looks like multiple close() calls, while reading files from DFS is failing in hadoop 0.14.
This was somehow not caught in hadoop 0.13.
The use case was to open a file on DFS like shown below
<code>
 FSDataInputStream
	fSDataInputStream =
	fileSystem.open(new Path(propertyFileName));
      Properties subProperties =
	new Properties();
      subProperties.
	loadFromXML(fSDataInputStream);
      fSDataInputStream.
	close();
</code>

This failed with an IOException
<exception>
EXCEPTIN RAISED, which is java.io.IOException: Stream closed
java.io.IOException: Stream closed
</exception>

The stack trace shows its being closed twice. While this used to work in hadoop 0.13 which
used to hide this.
Attached with this JIRA is a text file which has stack trace for both hadoop 0.13 and hadoop
0.14.

How should this be handled from a users point of view? 

Thanks
