[jira] Created: (HADOOP-4064) Hive should be able to create tables over binary flat files

Hive should be able to create tables over binary flat files
-----------------------------------------------------------

                 Key: HADOOP-4064
                 URL: https://issues.apache.org/jira/browse/HADOOP-4064
             Project: Hadoop Core
          Issue Type: Bug
          Components: contrib/hive
            Reporter: Joydeep Sen Sarma


Currently Hive only supports binary data embedded inside SequenceFiles. This is a request to enable this over flat files (for example a flat file containings sets of serialized binary records).

It is understood that this file cannot be split and that the user had to ensure that there is enough file level parallelism. maybe related to https://issues.apache.org/jira/browse/HADOOP-3787.

Hive also does not play nice with generic hadoop serialization mechanism (1986) - however that requires much more comprehensive change to SerDe interfaces.
