Hi,
Below are list of tuples generated after flattening a bag .
(day, age, name, address, ['k1#v1','k2#v2']),
(12/2,22,deepak,newyork, ['k1#v1','k2#v2']),
(12/3,22,deepak,newjersy, ['k1#v1','k2#v2'])
process = foreach inputs generate com.yahoo.peblpig.udf.InvokeProcess($0);
Here $0 some how gets only (day, age, name, address) and the map is skipped.
*How can i access the map? *
With
$1 i get "Out of bound access. Trying to access non-existent column: 1.
Schema {bytearray} has 1 column(s)",
$0.$1 throws java.lang.ClassCastException: java.lang.String cannot be cast
to org.apache.pig.data.Tuple
at
org.apache.pig.backend.hadoop.executionengine.physicalLayer.expressionOperators.POProject.getNext(POProject.java:389)
Also,
With
tuples = foreach flattenedTuples generate $0
generates
(day, age, name, address),
(12/2,22,deepak,newyork),
(12/3,22,deepak,newjersy)
After flatenning if i dump, i see the map in the resultant tuples, but $0
instead referring to entire tuple, referes only to data part (map skipped)
Regards,
Deepak
