> libhdfs3 is almost binary compatible with libhdfs. The missing bits are:
> * libhdfs3 does not define hdfsPread which nonetheless can be implemented in terms of hdfsTell, hdfsSeek and hdfsRead;
> * hdfsSync is called hdfsHSync in libhdfs3;
> * In libhdfs hdfsFlush flushes the internal buffer of the BufferedInputStream; in libhdfs3 it always flushes to HDFS, i.e. it does what hdfsHFlush should do.
