specification of SERDE in RCFile
Hi folks,

Through samples here and there, I've seen tables definitions using RCFile
storage specifying a SERDE in somecase, and sometimes not.

ie : sometimes ROW FORMAT SERDE
'org.apache.hadoop.hive.serde2.columnar.ColumnarSerDe' STORED AS RCFILE

some other times, only :  STORED AS RCFILE

My question : what happens if SERDE is not specified ? what's the default
behavior ?
Thank you
