> In HDFS, "dfs.namenode.fs-limits.max-directory-items" was introduced in HDFS-6102 to restrict max items of single directory, and the value of it can not be larger than the value of MAX_DIR_ITEMS. Since "ipc.maximum.data.length" was added in HADOOP-9676 and documented in HADOOP-13039 to make maximum RPC buffer size configurable, it's not proper to hard code the value of MAX_DIR_ITEMS in {{FSDirectory}}.
