-----------------------------
Summary: HoS DPP generates malformed plan when
hive.tez.dynamic.semijoin.reduction is on
Key: HIVE-16739
URL: https://issues.apache.org/jira/browse/HIVE-16739
Project: Hive
Issue Type: Bug
Components: Spark
Reporter: Rui Li
Assignee: Rui Li
HoS DPP currently can't handle dynamic semi join and will result in
{{ClassCastException org.apache.hadoop.hive.ql.plan.ReduceWork cannot be cast
to org.apache.hadoop.hive.ql.plan.MapWork}}.
We should either disable or implement it for HoS.
