Change subject: IMPALA-5003: Constant propagation in scan conjuncts
......................................................................
Patch Set 23:
So this tripped up on an functional.alltypes_datasource test, and the first
failure was obvious, but now there is a new failure mode which isn't obvious at
all, and unclear how it relates to this change:
[localhost:21000] > select string_col from alltypes_datasource
where string_col = 'VALIDATE_PREDICATES##id NOT_DISTINCT 1 && id DISTINCT_FROM
1 && id NOT_DISTINCT 1'
and 1 <=> id and 1 IS DISTINCT FROM id and 1 IS NOT DISTINCT FROM id;
Query: select string_col from alltypes_datasource
where string_col = 'VALIDATE_PREDICATES##id NOT_DISTINCT 1 && id DISTINCT_FROM
1 && id NOT_DISTINCT 1'
and 1 <=> id and 1 IS DISTINCT FROM id and 1 IS NOT DISTINCT FROM id
Query submitted at: 2017-04-26 17:20:43 (Coordinator: http://impala-dev:25000)
