- def deserializeLegacyObject[ObjectType](spark: SparkSession, path: String)(implicit arg0: ClassTag[ObjectType]): RDD[ObjectType]
Loads an object from a SequenceFile containing serialized objects.
Loads an object from a SequenceFile containing serialized objects. It tries to load the tuple across Scala version, handling serialVersionUID mismatches.
Adapted from sparkContext.objectFile:
"Load an RDD saved as a SequenceFile containing serialized objects, with NullWritable keys and BytesWritable values that contain a serialized partition."
- path
directory to the input data files, the path can be comma separated paths as a list of inputs
- returns
RDD representing deserialized data from the file(s)
