-----------------------------------
Summary: getReducersBucketing in SemanticAnalyzer may return more
than the max number of reducers
Key: HIVE-3898
URL: https://issues.apache.org/jira/browse/HIVE-3898
Project: Hive
Issue Type: New Feature
Components: Query Processor
Affects Versions: 0.11.0
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
getReducersBucketing rounds totalFiles / maxReducers down, when it should be
rounded up to the nearest integer.
E.g. if totalFiles = 60 and maxReducers = 21,
totalFiles / maxReducers = 2
totalFiles / 2 = 30
So the job will get 30 reducers, more than maxReducers.
