Harsh J commented on HADOOP-8615:
---------------------------------
Hi,
I noted that this changes the CompressionCodec interface, which would make it
an incompatible change for its users (as older code, downstream, would fail to
compile as they now may be missing a few method implementations).
Is it absolutely necessary to break compatibility to have just some information
over this exception?
> EOFException in DecompressorStream.java needs to be more verbose

> Affects Versions: 0.20.2
> Reporter: Jeff Lord
> Labels: patch
> Attachments: HADOOP-8615.patch, HADOOP-8615-release-0.20.2.patch,

> 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.
