Zhe Zhang updated HDFS-8191:
----------------------------
Status: Patch Available (was: Open)
The default upcasting from byte to integer will result in negative integers if
the first bit of the byte is 1. This causes {{read()}} to return -1, indicating
end of stream. This patch uses a byte mask for {{read()}} to always return the
actual byte with value 0~255.
> Fix byte to integer casting in SimulatedFSDataset#simulatedByte
