Subject [jira] [Commented] (HDFS-10368) Erasure Coding: Deprecate replication-related config keys
Date Wed, 19 Oct 2016 06:14:59 GMT

    [ 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.
dfs.replication.pending.timeout.sec	         =>   dfs.namenode.reconstruction.pending.timeout-sec
dfs.namenode.replication.pending.timeout-sec     =>   dfs.namenode.reconstruction.pending.timeout-sec

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?
