- *
- * Structure: H5FD_hdfs_fapl_t
- *
- * Purpose:
- *
- *     H5FD_hdfs_fapl_t is a public structure that is used to pass
- *     configuration information to the appropriate HDFS VFD via the FAPL.
- *     A pointer to an instance of this structure is a parameter to
- *     H5Pset_fapl_hdfs() and H5Pget_fapl_hdfs().
- *
- *
- *
- * `version` (int32_t)
- *
- *     Version number of the `H5FD_hdfs_fapl_t` structure.  Any instance passed
- *     to the above calls must have a recognized version number, or an error
- *     will be flagged.
- *
- *     This field should be set to `H5FD__CURR_HDFS_FAPL_T_VERSION`.
- *
- * `namenode_name` (const char[])
- *
- *     Name of "Name Node" to access as the HDFS server.
- *
- *     Must not be longer than `H5FD__HDFS_NODE_NAME_SPACE`.
- *
- *     TBD: Can be NULL.
- *
- * `namenode_port` (int32_t) TBD
- *
- *     Port number to use to connect with Name Node.
- *
- *     TBD: If 0, uses a default port.
- *
- * `kerberos_ticket_cache` (const char[])
- *
- *     Path to the location of the Kerberos authentication cache.
- *
- *     Must not be longer than `H5FD__HDFS_KERB_CACHE_PATH_SPACE`.
- *
- *     TBD: Can be NULL.
- *
- * `user_name` (const char[])
