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.
