ZHUO ZHANG updated ARROW-13981:
-------------------------------
Description:
Looks like the buffer copy logic doesn't work for BitVector, even though the
BitVector is from BaseFixedWidthVector. I created two VectorSchemaRoot (target
empty), calling
{code:java}
VectorSchemaRootAppender.append(target, source);{code}
then reading from the target didn't give me correct result.
Hope to get confirmation from experts that this is a problem in Apache Arrow,
if yes, wondering if there is a workaround (tried using copyFromSafe as well
and it doesn't work either)
