Advertisements

This function is used to generate DateTime object of the current time.

Syntax

Here is the syntax of CurrentTime() function.

grunt> CurrentTime() 

Example

Assume that there is a file named date.txt in the HDFS directory /pig_data/. This file contains the date-of-birth details of a particular person, id, date, and time.

date.txt

001,1989/09/26 09:00:00
002,1980/06/20 10:22:00
003,1990/12/19 03:11:44 

And, we have loaded this file into Pig with a relation named date as shown below.

grunt> date_data = LOAD 'hdfs://localhost:9000/pig_data/date.txt' USING PigStorage(',')
   as (id:int,date:chararray);

Following is an example of the CurrentTime() function. Here we are generating the current time.

grunt> currenttime_data = foreach todate_data generate CurrentTime();

The result of the statement will be stored in the relation named currenttime_data. Verify the content of this relation using the Dump operator.

grunt> Dump currenttime_data;
