Subject [jira] [Commented] (HADOOP-8615) EOFException in DecompressorStream.java needs to be more verbose
Date Mon, 05 Nov 2012 19:22:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13490842#comment-13490842
] 

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

bq. Please let me know for any feedback.

Sorry for the delay!

A few more whitespace fixups:
- make sure {{) throws}} has a space between the ) and "throws". (2 examples in this patch)
- still a few argument lists missing a space after "," for example {{return createInputStream(in,
null,fileName);}}.
- also a few argument lists with extra spaces before "," for example {{Decompressor decompressor
, String fileName}}
- extra space in {{protected  String fileName}}
- extra space in {{this.fileName =  fileName}}
- missing spaces in {{\+"file = "\+this.fileName}}, always put spaces on both sides of "\+"
and other operators. also we generally put the "+" on the previous line for a string continuation
like this one.
- missing space in {{if ((b1 | b2 | b3 | b4) < 0\)\{}} before "{"
- missing space in {{String fileName ="fileName";}} after "="

Thanks again for working on this enhancement!

> 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.
