James Clampffer updated HDFS-9368:
----------------------------------
Attachment: HDFS-9368.HDFS-8707.002.patch
New patch:
-file ops return status rather than posix style numbers. Changed parameters
like nbytes of read and offset for seek to pointers to be used as in/out params.
e.g.
size_t count = 100; how many bytes you'd like to read
MyFileHandle::read(mybuffer, &count);
count now set to how many bytes were read
-Changed Whence to ios_base::seekdir enum
-moved FileHandle constructor to .cc file
-InputStream::get_file_length now const and returns a uint64_t
-got rid of comment around cast
> Implement reads with implicit offset state in libhdfs++
