hdfsAvailable returning int

Hi,

Since hdfsAvailable's return type (
https://github.com/apache/hadoop/blob/3b46aae977e078cf7eb5e6bbbc55aca7cecee4c7/hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfs/include/hdfs/hdfs.h#L824)
is int, it is difficult to accurately get the size of large files using the
C API. Are there any workarounds?

Thank you,

To get the size of a file, you should use hdfsGetPathInfo instead.
