> When reading an arrow file with buffers LZ4-compressed with multiple frames, we get
> {code:java}
> OSError: Lz4 compressed input contains more than one frame
> {code}
> Attached is an example of such a file, which can be opened with
> {code:java}
> import pyarrow.ipc
> with pa.ipc.open_file("b.arrow") as reader:
>     print(reader.get_batch(0))
> {code}
> that fails with the error above.
> The LZ4 frame supports multiple frames and we do not refer that only one frame should be on a buffer as part of the spec.
