> 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.
