----------------------------------------------
Summary: Disable RS deduplication step in Optimizer if it is run
in TezCompiler
Key: HIVE-23298
URL: https://issues.apache.org/jira/browse/HIVE-23298
Project: Hive
Issue Type: Improvement
Components: Physical Optimizer
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
HIVE-20703 introduced an additional RS deduplication step in TezCompiler. We
could possibly try to disable the one that runs in {{Optimizer}} if we are
using Tez so we do not run the optimization twice.
This issue is to explore that possibility.
