Prem Sagar Gali updated ARROW-11872:
------------------------------------
Description:
Whenever we try to create an array or a Table from a GPU buffer we get the
following Invalid missing values buffer error.
{code:java}
pyarrow/table.pxi:485: in pyarrow.lib.chunked_array
???
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ > ???
E pyarrow.lib.ArrowInvalid: In chunk 0: Invalid: Missing values buffer in
non-empty arraypyarrow/error.pxi:84: ArrowInvalid{code}
This is because the GPU buffers aren't passing the following validation check:
[https://github.com/apache/arrow/blob/7be266be98d08214ef4b3f067059b6e6a8a6e5c0/cpp/src/arrow/array/validate.cc#L183]
But this has to be changed to something like:
{code:java}
static bool IsBufferValid(const ArrayData& data, int index)
{ return data.buffers[index] != nullptr && (data.buffers[index]->is_cpu() ?
data.buffers[index]->data() != nullptr : true); }
{code}
