----------------------------------------
Summary: DataInputViewStream skip returns wrong value
Key: FLINK-11915
URL: https://issues.apache.org/jira/browse/FLINK-11915
Project: Flink
Issue Type: Bug
Reporter: Andrew Prudhomme
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.
