Anatoli Shein commented on HDFS-10511:
--------------------------------------
Update:
we decided to go with the following:
0 on success (or other returned value specific to the function)
-1 on failure (and set errno globally)
> libhdfs++: make error returning mechanism consistent across all hdfs
> operations
