Subject [jira] [Commented] (HADOOP-8615) EOFException in DecompressorStream.java needs to be more verbose
Date Wed, 25 Jul 2012 07:03:35 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13422046#comment-13422046
] 

thomas sebastian commented on HADOOP-8615:
------------------------------------------

As the descriptions says, we need the file name in the exception printed.I think of a simple
way to pass the filename to the constructor of the DecompressorStream. For this a new overloaded
constructor is to be created. 
Then we can use the fileName in the exception message. As part of creating a new overloaded
constructor, we would require to make a few changes also in some other files as well.

It worked for one of my implementations.

>          Issue Type: Bug
>          Components: io
>    Affects Versions: 0.20.2
>            Reporter: Jeff Lord
>
> In ./src/core/org/apache/hadoop/io/compress/DecompressorStream.java
> The following exception should at least pass back the file that it encounters this error
in relation to:
>   protected void getCompressedData() throws IOException {
>     checkStream();
>     int n = in.read(buffer, 0, buffer.length);
>     if (n == -1) {
>       throw new EOFException("Unexpected end of input stream");
>     }
> This would help greatly to debug bad/corrupt files.
