> Current description for "dfs.namenode.num.extra.edits.retained" and
> "dfs.namenode.num.checkpoints.retained" properties on hdfs-default.xml is not
> clear on how much and which files will be kept on namenodes meta-data
> directory.
> For "dfs.namenode.num.checkpoints.retained", it's not clear that it applies
> to the number of "fsimage_*" files.
> For "dfs.namenode.num.extra.edits.retained", it's not clear the value set
> indirectly applies to "edits_*" files, and how the configured value
> translates into the number of edit files to be kept.
