Zhe Zhang reopened HDFS-8982:
-
bq. The so-called getPerferredBlockReplication() records the maximum
replication factor of the file w.r.t. the current and all snapshot state of the
file.
[~wheat9] By using "so-called" I take that you agree we should at least give it
a better name (which was suggested in the JIRA description). Reopening the
issue based on the consensus.
> Consolidate getFileReplication and getPreferredBlockReplication in INodeFile

> Key: HDFS-8982

>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.
