------------------------------------------
Summary: Improve description for
"dfs.namenode.num.extra.edits.retained" and
"dfs.namenode.num.checkpoints.retained" properties on hdfs-default.xml
Key: HDFS-7752
URL: https://issues.apache.org/jira/browse/HDFS-7752
Project: Hadoop HDFS
Issue Type: Improvement
Components: documentation
Affects Versions: 2.6.0
Reporter: Wellington Chevreuil
Assignee: Wellington Chevreuil
Priority: Minor
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.
