---------------------------------------
Summary: HashValuePartitioner has skew when there is only map
fields
Key: PIG-5088
URL: https://issues.apache.org/jira/browse/PIG-5088
Project: Pig
Issue Type: Bug
Reporter: Rohini Palaniswamy
Assignee: Rohini Palaniswamy
Fix For: 0.17.0, 0.16.1
One user who just did union of map fields, got a skew with everything going
to one input file as hashcode for map was calculated on the size. [~knoguchi]
pointed out that my assumption of map hashcode being non-deterministic and can
change with jdk versions is wrong as it just does a sum of hashcode of its
entries.
