Cheolsoo Park resolved PIG-3890. -------------------------------- Resolution: Not a Problem Closing the jira as it is not a problem. Order by works fine. I guess the issue the user faced is probably environment-related (e.g. Hadoop/Tez/Pig installation). > Global sort is not working (order by) Pig over Tez > -------------------------------------------------- > > Key: PIG-3890 > URL: https://issues.apache.org/jira/browse/PIG-3890 > Project: Pig > Issue Type: Sub-task > Environment: Linux > Reporter: Nagamallikarjuna > Priority: Minor > Labels: Global, pig, sort, tez > > I tried to run pig scripts on top of Apache Tez.
