Description

hdfs_find uses u_int32_t type for storing the value for the max-depth command line argument - https://github.com/apache/hadoop/blob/a631f45a99c7abf8c9a2dcfb10afb668c8ff6b09/hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfspp/tools/hdfs-find/hdfs-find.cc#L43.
The type u_int32_t isn't standard, isn't available on Windows and thus breaks cross-platform compatibility. We need to replace this with uint32_t which is available on all platforms since it's part of the C++ standard.
