Hive UDF - Convert Date to Unix Timestamp
Background
This little UDF will convert a date, in any specified format, into a unix timestamp. To specify the date just edit the string in the SimpleDateFormat to your liking. So here is how we did it.
I have also left in the imports and you will need to find the jar files that contain these classes.

Implementation
package allan.DtoT;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import org.apache.hadoop.hive.ql.exec.UDF;
public class DateToTime extends UDF{
public long evaluate(final String d){
try{
SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
return sf.parse(d.trim()).getTime();
} catch (ParseException pe) {return -1;}
}
}
