---------------------------------
Summary: Document dfs.namenode.resource.*
Key: HDFS-4227
URL: https://issues.apache.org/jira/browse/HDFS-4227
Project: Hadoop HDFS
Issue Type: Bug
Components: documentation
Reporter: Eli Collins
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 (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.
