-------------------------------------------
Summary: [C++] Replace With Mask, wrong result
Key: ARROW-14795
URL: https://issues.apache.org/jira/browse/ARROW-14795
Project: Apache Arrow
Issue Type: Bug
Reporter: Alvin Chunga Mamani
I'm working in ARROW-1699 and using the method *{{ReplaceWithArrayMask}}* for
replace the nulls using a generated mask, but the method gave me unexpected
results when the input Array contains nulls and this nulls are replaced with
values.
When testing this special Test on *vector_test_replace_test.cc*
{code:java}
this->Assert(ReplaceWithMask, this->array("[1, null, 1]"),
this->mask("[false, true, false]"),
this->array("[7]"),
this->array("[1, 7, 1]"));{code}
The result is:
{code:java}
Actual:
[
1,
null,
1
]{code}
And debugging the code, the output values is correct, but the null_bitmap
isn't updated and keep the original null_bitmap
In the file *{{vector_replace.cc}}* on line 202, the bitmap is updated only
for turnoff the null replacement values

This is and expected behavior or an issue on *{{ReplaceWithArrayMask}}* ?
