Hello Marcel Kornacker,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/5050
to look at the new patch set (#2).
Change subject: IMPALA-4470: Avoid creating a NumericLiteral from
NaN/infinity/-0.
......................................................................
IMPALA-4470: Avoid creating a NumericLiteral from NaN/infinity/-0.
Our NumericLiteral is backed by a BigDecimal which cannot
represent the special float values NaN, infinity or negative zero.
As a result, when evaluating constant expressions from the FE we
hit an exception when trying to create a NumericLiteral from
a NaN or infinity value. Before, negative zero would silently
get converted to zero which is dangerous.
The fix is to treat the expr evaluation as a failure and not
replace the constant Expr with a LiteralExpr.
