Subject [jira] [Commented] (HDFS-9869) Erasure Coding: Rename replication-based names in BlockManager to more generic [part-2]
Date Tue, 19 Apr 2016 08:19:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9869?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15247363#comment-15247363

Rakesh R commented on HDFS-9869:

Thanks [~zhz] for the review comments.
bq. Chain deprecation below. Maybe we should combine them?
How about keeping only the recent property name {{| dfs.namenode.replication.pending.timeout-sec
| dfs.namenode.reconstruction.pending.timeout-sec |}} and remove the old deprecated property
{{| dfs.replication.pending.timeout.sec | dfs.namenode.replication.pending.timeout-sec |}}
entry considering that this property {{dfs.replication.pending.timeout.sec}} was deprecated
long back and now we will be releasing {{3.0.0}} version?

bq. As a followup we should also deprecate other replication-related config keys.
Shall we do this deprecation through another follow-up jira task?

bq. Maybe we can also keep the "excess" in excessRedundancyMap? This matches better with the
I agree and will keep the term {{excess}} while preparing next patch.
