[jira] [Created] (IMPALA-6146) Rethink HdfsTextScanner::FillByteBuffer() extension point

Tim Armstrong created IMPALA-6146:
-------------------------------------

             Summary: Rethink HdfsTextScanner::FillByteBuffer() extension point
                 Key: IMPALA-6146
                 URL: https://issues.apache.org/jira/browse/IMPALA-6146
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
            Reporter: Tim Armstrong
            Priority: Minor


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.
