[jira] Created: (HADOOP-674) Hadoop records should provide
comvenient APIs for serialization/deserialization
Hadoop records should provide comvenient APIs for serialization/deserialization
-------------------------------------------------------------------------------
Key: HADOOP-674
URL: http://issues.apache.org/jira/browse/HADOOP-674
Project: Hadoop
Issue Type: Improvement
Reporter: Runping Qi
I found the following APIs are very convenient to use and should be part of the generated class from Jute IDL :
public BytesWritable serialize(String format);
public void deserialize(BytesWitable data, String format);
public static MyRecordJT deserialize(BytesWitable data, String format);

[jira] Commented: (HADOOP-674) Hadoop records should provide

Milind Bhandarkar commented on HADOOP-674:
------------------------------------------
One can easily use ByteArrayOutputStream to serialize and deserialize out of current generated code. Addition of above API's will unnecessarily increase complexity of generated code. Is there any strong reason to believe that the above API will be a common case for usage ? In light of HADOOP-941, this API will increase Hadoop Record I/O's dependence on Hadoop.

Yes, the first two methods should definitely be part of the Record interface.
