Examples of org.apache.hadoop.hive.serde2.AbstractSerDe.initialize()

org.apache.hadoop.hive.serde2.AbstractSerDe.initialize()
Initialize the SerDe. By default, this will use one set of properties, either the table properties or the partition properties. If a SerDe needs access to both sets, it should override this method. Eventually, once all SerDes have implemented this method, we should convert it to an abstract method. @param configuration Hadoop configuration @param tableProperties Table properties @param partitionProperties Partition properties @throws SerDeException
