> Improve Invalid File Format Error Message
> -----------------------------------------
>
> Key: AVRO-2061
> URL: https://issues.apache.org/jira/browse/AVRO-2061
> Project: Avro
> Issue Type: Improvement
> Components: java
> Affects Versions: 1.9.0, 1.8.2
> Reporter: BELUGA BEHR
> Assignee: BELUGA BEHR
> Priority: Trivial
> Attachments: AVRO-2061.1.patch, AVRO-2061.2.patch

> {code:title=org.apache.avro.file.DataFileStream<D>}
> try {
> vin.readFixed(magic); // read magic
> } catch (IOException e) {
> throw new IOException("Not a data file.", e);
> }
> if (!Arrays.equals(DataFileConstants.MAGIC, magic))
> throw new IOException("Not a data file.");
> {code}
> Please consider improving the error message here. I just saw a MapReduce job
> fail with an IOException with the message "Not a data file." There was
> definitely data files in the input directory, however, they were not Avro
> files. It would have been much more helpful if it told me that.
