Haohui Mai resolved HDFS-8982.
------------------------------
Resolution: Won't Fix
The behavior is expected.
{{getFileReplication()}} records the replication factor of the "current"
(w.r.t. snapshot state) replicate factor of the file.
The so-called {{getPerferredBlockReplication()}} records the maximum
replication factor of the file w.r.t. the current and all snapshot state of the
file.
> Consolidate getFileReplication and getPreferredBlockReplication in INodeFile

> Key: HDFS-8982
> URL: https://issues.apache.org/jira/browse/HDFS-8982
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 2.7.1
> Reporter: Zhe Zhang
>
> Currently {{INodeFile}} provides both {{getFileReplication}} and
> {{getPreferredBlockReplication}} interfaces. At the very least they should be
> renamed (e.g. {{getCurrentFileReplication}} and
> {{getMaxConfiguredFileReplication}}), with clearer Javadoc.
> I also suspect we are not using them correctly in all places right now.
