Subject [jira] [Commented] (HDFS-8356) Document missing properties in hdfs-default.xml
Date Mon, 04 Apr 2016 04:53:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15223658#comment-15223658
] 

Akira AJISAKA commented on HDFS-8356:
-------------------------------------

Thanks [~rchiang] for the update! Additional comments:
{code}
    // Fully deprecated properties?
    configurationPropsToSkipCompare
        .add("dfs.client.file-block-storage-locations.num-threads");
    configurationPropsToSkipCompare
        .add("dfs.client.file-block-storage-locations.timeout.millis");
(snip)
    configurationPropsToSkipCompare
        .add("dfs.namenode.replication.max-streams-hard-limit");
{code}
1. These properties are not deprecated. They should be documented, or commented as {{TODO:
document these properties}}.

{code}
    configurationPropsToSkipCompare
        .add("dfs.namenode.hosts");
    configurationPropsToSkipCompare
        .add("dfs.namenode.hosts.exclude");
{code}
2. These properties can be removed.
