Robert Metzger updated FLINK-11915:
-----------------------------------
Component/s: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
> DataInputViewStream skip returns wrong value
> --------------------------------------------
>
> Key: FLINK-11915
> URL: https://issues.apache.org/jira/browse/FLINK-11915
> Project: Flink
> Issue Type: Bug
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile),
> Runtime / Operators
> Reporter: Andrew Prudhomme
> Priority: Minor
>
> The
> flink-core:org.apache.flink.api.java.typeutils.runtime.DataInputViewStream
> overrides the InputSteam skip function. This function should be returning the
> actual number of bytes skipped, but there is a bug which makes it return a
> lower value.
> The fix should be something simple like:
> {code:java}
> - return n - counter - inputView.skipBytes((int) counter);
> + return n - (counter - inputView.skipBytes((int) counter));
> {code}
> For context, I ran into this when trying to decode an Avro record where the
> writer schema had fields not present in the reader schema. The decoder would
> attempt to skip the unneeded data in the stream, but would throw an
> EOFException because the return value was wrong.
