UDF Fails to operate on Different Columns #4

Open akhld opened 10 years ago

akhld commented 10 years ago

UDF output is not proper, it is operating on the first column even if you specify some other column

Eg: REGISTER /home/akhld/mobi/temp/pig/demo/tutorial.jar; A = load 'hdfs://localhost:9000/input/' USING PigStorage('\t') AS (user:chararray, time:int, query:chararray); B = FOREACH A GENERATE org.apache.pig.tutorial.ToLower(query) as query; STORE B INTO '/tmp/query';

Fails to Operate on "query" column, but the processing happens on "user" column.
