Ian Cook created ARROW-13412:
--------------------------------
Summary: [C++] and_kleene, or_kleene return null on Scalar and
multi-chunk ChunkedArray
Key: ARROW-13412
URL: https://issues.apache.org/jira/browse/ARROW-13412
Project: Apache Arrow
Issue Type: Bug
Components: C++
Affects Versions: 4.0.1
Reporter: Ian Cook
When you pass a Scalar and a ChunkedArray with 2+ chunks to the {{or_kleene}}
or {{and_kleene}} kernel, it returns all {{null}} in the result.
Demonstrating this with the R bindings:
{code:java}
> call_function("or_kleene", Scalar$create(TRUE), ChunkedArray$create(c(T,F,T),
> c(F,T,F)))
ChunkedArray
[
[
null,
null,
null,
null,
null,
null
]
]{code}
Compare to the following which all work as one would expect:
Scalar and ChunkedArray with only one chunk (works as expected):
{code:java}
> call_function("or_kleene", Scalar$create(TRUE), ChunkedArray$create(c(T,F,T)))
ChunkedArray
[
[
true,
true,
true
]
]
{code}
Scalar and Array (works as expected):
{code:java}
> call_function("or_kleene", Scalar$create(TRUE), Array$create(c(T,F,T)))
Array
<bool>
[
true,
true,
true
]
{code}
Two ChunkedArrays (works as expected):
{code:java}
> call_function("or_kleene", ChunkedArray$create(c(T,NA,T), c(F,F,T)),
> ChunkedArray$create(c(T,NA,T), c(F,F,T)))
ChunkedArray
[
[
true,
null,
true,
false,
false,
true
]
]
{code}
