Robert Goodman resolved AVRO-252.
----------------------------------
Resolution: Invalid
Fix Version/s: 1.3.0
I'm marking this issue as Invalid because of the changes made to
DataFilereader.java in the trunk. The intent of adding the tell() method was to
allow a record reader to determine when it had reached the end of the file
split and the pastSync(position) method now provides this functionality.
> Add a tell() method to DataFileReader.java which returns the position in a
> file

> Key: AVRO-252
> URL: https://issues.apache.org/jira/browse/AVRO-252
> Project: Avro
> Issue Type: Improvement
> Components: java
> Reporter: Robert Goodman
> Priority: Minor
> Fix For: 1.3.0
>
>
> A RecordReader needs to be able to get the current position in the file to
> determine when it has reached the end of a file split and to handle errors.
> This improvement will add a tell() method to DataFileReader.java which
> returns the position in a file. The position returned by the tell() method
> will only change when crossing a block boundary in a file. The position does
> not increment as DataFileReader.java processes data within a block.
> This will allow a RecordReader to do a simple check for when the position
> returned by tell() is past the end of a file split to know when to stop
> reading. The RecordReader will also be able to recover from errors by calling
> sync(tell()) to sync to the next block and attempting to continue reading.
