InternalSortedBag should take care of sort order
------------------------------------------------
Key: PIG-1195
URL: https://issues.apache.org/jira/browse/PIG-1195
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.6.0
Reporter: Daniel Dai
Fix For: 0.6.0
InternalSortedBag always use ascending order. We shall obey the sort order as
specified in the script.
For example, the following script does not do the right thing if we turn off
secondary sort (which means, we will rely on InternalSortedBag to sort):
{code}
A = load 'input' as (a0:int);
B = group A ALL;
C = foreach B {
D = order A by a0 desc;
generate D;
};
dump C;
{code}
If we run it using the command line "java -Xmx512m
-Dpig.exec.nosecondarykey=true -jar pig.jar 1.pig".
The sort order for D is ascending.
