      Description

      Let's document dfs.namenode.resource.* in hdfs-default.xml and a section the in the HDFS docs that covers local directories.

      dfs.namenode.resource.check.interval - the interval in ms at which the NameNode resource checker runs (default is 5000)

      dfs.namenode.resource.du.reserved - the amount of space to reserve/require for a NN storage directory (default is 100mb)

      dfs.namenode.resource.checked.volumes - a list of local directories for the NN resource checker to check in addition to the local edits directories (default is empty).

      dfs.namenode.resource.checked.volumes.minimum - the minimum number of redundant NN storage volumes required (default is 1). If no redundant resources are available we don't enter SM if there are sufficient required resources.
