-----------------------------------
njain has commented on the revision "HIVE-3849 [jira] Columns are not extracted
for multi-groupby single reducer case somtimes".
INLINE COMMENTS
ql/src/java/org/apache/hadoop/hive/ql/parse/SemanticAnalyzer.java:3537 Do you
think it would be easier to change genAllExprNodeDesc to return
Map<ASTNode, ExprNodeDesc> ?
It might involve a change in TypeCheckProcFactory, but it will make it
much more readable.
ql/src/java/org/apache/hadoop/hive/ql/parse/SemanticAnalyzer.java:3548 nit:
formatting
ql/src/java/org/apache/hadoop/hive/ql/parse/SemanticAnalyzer.java:3569 Can
you add correct comments for this function ?
The predicates will be removed from mapping if they are passed in keys
ql/src/test/queries/clientpositive/groupby_multi_single_reducer3.q:8 It might
be a good idea to add a test where the grouping key is present in
the where clause.
