Key: ARROW-8756
URL: https://issues.apache.org/jira/browse/ARROW-8756
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Kazuaki Ishizaki
The following two tests in arrow-utility-tests cause failures on big-endian platforms
{code}
[----------] 5 tests from Bitmap
[ RUN ] Bitmap.ShiftingWordsOptimization
/home/ishizaki/Arrow/arrow-rle/cpp/src/arrow/util/bit_util_test.cc:1133: Failure
Expected equality of these values:
BitUtil::GetBit(bytes, i)
Which is: false
bool((word >> i) & 1)
Which is: true
[ FAILED ] Bitmap.ShiftingWordsOptimization (0 ms)
...
[ RUN ] Bitmap.VisitWordsAnd
/home/ishizaki/Arrow/arrow-rle/cpp/src/arrow/util/bit_util_test.cc:1289: Failure
Value of: BitmapEquals(actual_buffer->data(), min_offset, expected_buffer->data(), 0, num_bits)
Actual: false
Expected: true
left_offset:1 bits:8191 right_offset:0
