Subject [jira] [Commented] (HADOOP-8615) EOFException in DecompressorStream.java needs to be more verbose
Date Tue, 06 Nov 2012 21:10:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13491828#comment-13491828
] 

Andy Isaacson commented on HADOOP-8615:
---------------------------------------

bq. To incorporate these fixes, should I take the latest from the trunk again,

Good question.  Your patch will be applied against trunk when it's committed, so in some cases
you will need to make changes to merge with trunk, and there's never a downside to refreshing
your patch against trunk.

>From the patch file formatting it looks like you're using svn, so you can probably just
"svn up" and resolve any merge conflicts.  I use git, and use "git pull --rebase" to get a
similar effect on my working branches.

> 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.
