----------------------------------
Summary: Vectorization: different results between MR and Tez for
aggregation functions (variance, var_pop, var_samp, std, stddev, etc)
Key: HIVE-8063
URL: https://issues.apache.org/jira/browse/HIVE-8063
Project: Hive
Issue Type: Bug
Reporter: Matt McCline
Assignee: Matt McCline
Priority: Critical
When running vectorized_timestamp_funcs.q with aggregation functions (listed in
title), the results were 0 on Tez and non-zero on MR. The aggregatesDefinition
table in VectorizationContext.java currently disallows timestamp and date for
those functions.
