Resolution: Fixed
Fix Version/s: 1.2.0
> FixedLengthBinaryRecordReader should readFully
> ----------------------------------------------

> Key: SPARK-4222
> URL: https://issues.apache.org/jira/browse/SPARK-4222
> Project: Spark
> Issue Type: Bug
> Reporter: Jascha Swisher
> Assignee: Jascha Swisher
> Priority: Minor
> Fix For: 1.2.0
>
>
> The new FixedLengthBinaryRecordReader currently uses a read() call to read
> from the FSDataInputStream, without checking the number of bytes actually
> returned. The currentPosition variable is updated assuming that the full
> number of requested bytes are returned, which could lead to data corruption
> or other problems if fewer bytes come back than requested.
