[jira] Created: (MAPREDUCE-1524) Support for CLOB and BLOB values larger than can fit in memory

Support for CLOB and BLOB values larger than can fit in memory
--------------------------------------------------------------

                 Key: MAPREDUCE-1524
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1524
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: contrib/sqoop
            Reporter: Aaron Kimball
            Assignee: Aaron Kimball


The patch in MAPREDUCE-1446 provides support for "inline" CLOB and BLOB values which can be fully materialized. Values which are too big for RAM should be written to separate files in HDFS and referenced in an indirect fashion; access should be provided through a stream.
