Rohini Palaniswamy commented on PIG-4683: ----------------------------------------- bq. No, because currently SecondaryKeyOptimizerTez does not optimize cogroup. But if we enable that in Tez, we will face the same issue. We should have a jira to fix SecondaryKeyOptimizerTez to support it. Even if it was supported it should not be an issue as POShuffleTezLoad does not use PeekedBag like POPackage > Nested order is broken after PIG-3591 in some cases > --------------------------------------------------- > > Key: PIG-4683 > URL: https://issues.apache.org/jira/browse/PIG-4683 > Project: Pig > Issue Type: Bug > Components: impl > Reporter: Daniel Dai > Assignee: Daniel Dai > Fix For: 0.16.0, 0.15.1 > > Attachments: PIG-4683-1.patch > > > The following script fail after PIG-3591. > {code} > a = load '1.txt' using PigStorage(',') as (a0:chararray, a1:chararray); > b = load '2.txt' as (b0:chararray); > c = cogroup b by b0, a by a0; > d = foreach c { > a_sorted = order a by a1 desc; > generate group, a_sorted, b; > } > dump d; > {code} > 1.txt > a,0 > a,2 > a,1 > 2.txt > a > Expected: > {code} > (a,{(a,1),(a,2),(a,0)},{(a)}) > {code} > Actual: > {code} > (a,{(a,2),(a,1),(a,0),(a)},{}) > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
