> The HDFS text scanner allows extension via subclassing and overriding FillByteBuffer(). FillByteBuffer() is poorly encapsulated from the rest of the text scanner implementation - it modifies several member variables, which makes it hard to fix bugs like IMPALA-6137. We should come up a better defined interface.
