Anatoli Shein commented on HDFS-10672:
--------------------------------------
Thank you for your commnets, [~bobhansen]. I have fixed the following issues in
the new patch:
* The last_bytes_read parameter should be set to sizeof(buf) each time. That
makes this a very messy and error-prone API; buf_size and bytes_read should be
different parameters. Let's fix it as part of this bug.
(/) Done. Now PositionRead takes 4 parameters.
* We should distinguish between normal end-of-file failures to read and "there
was an error" status. What should we expect when we get to EOF? We should
document that in the headers.
(/) Done. I created a new error: invalid offset, which is set when trying to
begin a read after the EOF, and documented this in the headers.
