Raghu Angadi commented on HADOOP-2067:
--------------------------------------
in 0.13.x multiple close() was allowed unintentionally I think, second close
was hidden from FSInputStream by BufferedInputStream in between.
Many Java streams seem to tolerate closing more than once, may be Hadoop should
too.
> 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
> Attachments: stack_trace_13_and_14.txt
>
>
> 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
