Subject [jira] [Commented] (HDFS-10368) Erasure Coding: Deprecate replication-related config keys

    [ https://issues.apache.org/jira/browse/HDFS-10368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15587810#comment-15587810

Rakesh R commented on HDFS-10368:
---------------------------------

Thanks [~andrew.wang] for the reminder. Earlier we had identified one property and deprecated
it as part of HDFS-9869.
{code}
https://hadoop.apache.org/docs/r3.0.0-alpha1/hadoop-project-dist/hadoop-common/DeprecatedProperties.html
dfs.replication.pending.timeout.sec	         =>   dfs.namenode.reconstruction.pending.timeout-sec
dfs.namenode.replication.pending.timeout-sec     =>   dfs.namenode.reconstruction.pending.timeout-sec
{code}

Like mentioned, this jira to revisit the replication related configs, following are few replication
config items. Do we need to modify any of these to reconstruction or redundancy? I remember
somewhere we dicussed to consider EC internal blocks are a special form of replicas, do we
documented the same anywhere?
{code}
dfs.namenode.replication.considerLoad
dfs.namenode.replication.considerLoad.factor
dfs.namenode.replication.min
dfs.namenode.replication.interval
dfs.namenode.replication.work.multiplier.per.iteration
dfs.namenode.replication.max-streams
dfs.namenode.replication.max-streams-hard-limit
{code}

in order to make it more meaningful.
