----------------------------------
Summary: Favor serde2.io Writable classes over hadoop.io ones
Key: HIVE-4653
URL: https://issues.apache.org/jira/browse/HIVE-4653
Project: Hive
Issue Type: Sub-task
Components: Query Processor
Affects Versions: vectorization-branch
Reporter: Remus Rusanu
Priority: Minor
"The Writables are originally from org.apache.hadoop.io. I tend to assume that
they have been re-defined in hive if the original implementation was not
considered good enough.
However, I don't understand why some are defined twice in hive itself. I
noticed that ByteWritable in o.a.h.hive.ql.exec is not being used anywhere. The
ByteWritable in serde2.io is being referred to in bunch of places. Therefore, I
would suggest to just use the one in serde2.io."
