Hi All,I have the following problem:
This is a statement in my Pig script. cust_joined = JOIN cust_filtered BY (LOW,
HIGH, NORMAL), cust_conversion BY (Low, High, Normal);
When Datatypes are chararray for all these fields. So null should be
interpreted as 'null', right?
cust_filtered includes the following entries -- I stored this relation and
these are in that file:cust_id Val1 Val2 Year Low High
Normal Prod-code1925635222 16.2 61.2 2013 null null <=6.9
1234548-59253821456 16.8 65.8 2014 null null <7.0 4548567-9
cust_conversion includes the following entries -- I stored this relation and
these are in that file:Low High Normal Cust-Session Pricenull null
<=6.9 ABC-1234 16.9null null <=7.0 PQR-4567 87.0
Unfortunately cust_joined relation is empty. Any help with this will be great.
