> Components: documentation
> Affects Versions: 0.20.1
> Reporter: freestyler

> in HADOOP/src/c++/libhdfs/hdfs.h
> The following function document is incorrect:
> /* @param mtime new modification time or 0 for only set access time in
> seconds
> @param atime new access time or 0 for only set modification time in
> seconds
> */
> int hdfsUtime(hdfsFS fs, const char* path, tTime mtime, tTime atime);
> Currently, setting mtime or atime to 0 has no special meaning. That is, file
> last modified time will change to 0 if the mtime argument is 0.
> libhdfs should translate mtime = 0 or atime = 0 to the special value -1,
> which in HDFS means "don't change this time."
