liyunzhang_intel updated PIG-4284:
----------------------------------
Attachment: PIG-4284_2.patch
PIG-4284.patch is based on 4ca0ffb - (HEAD, origin/spark, spark) PIG-4568: Fix
unit test failure in TestSecondarySortSpark.
Changes are:
1. modify equals() and hashCode() in IndexedKey. In previous patch, if the key
of a IndexKey is not null, i only assign the key value, the index value is
default value 0. In current patch, i assign the key and index value.
in equals(), compare the index and value matching following cases:
{code}
* There are two possible cases when two tuples are compared:
* 1) Compare tuples of same table (same index)
* 2) Compare tuples of different tables (different index values)
* In 1)
* key1 key2 equal?
* foo null N
* null foo N
* foo foo Y
* null null Y
*
* In 2)
* key1 key2 equal?
* foo null N
* null foo N
* foo foo Y
* null null N
{code}
