We are currently debugging a pig script. we'd like to define a tuple in the Pig file directly (instead of the basic "Load" function).

Solution 1:

  • Its is difficult to do in pig script as it currently stands.If we just want to debug create a file in hadoop and load that.

Solution 2:

The following step can also do the job:

Create a file With one empty row ans store it to your HDFS. - load it : Line = load /user/toto/onelinefile USING .. - create own datas : foreach line generate 'wiki' as name, 22 as age;
