If your old data are stored in Hive, you can just use "insert
overwrite" to convert the data.
If you want your data be directly generated to a RCFile, rcfile has
its own Writer API. You can find some examples from TestRCFile
testcase from Hive..

Hi,
I want to convert data stored in a hadoop sequence file to
BytesRefArrayWritable so that I can use RCFileOutputFormat and create an
RCFile.
My data contains integers,strings and hashmaps. I guess I don't have to
write my own serializer/deserializer for these. I tried using the
ColumnarS
