----------------------------
Summary: Rename getBlockReplication to getPreferredBlockReplication (was: Rename getBlockReplication to getPreferredBlockStorageNum)
> Rename getBlockReplication to getPreferredBlockReplication

> Key: HDFS-8255
> URL: https://issues.apache.org/jira/browse/HDFS-8255
> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 2.8.0
> Reporter: Zhe Zhang
> Assignee: Zhe Zhang

>
> We should rename {{BlockCollection#getBlockReplication}} to {{getPreferredBlockStorageNum}} for 2 reasons:
> # Currently, this method actually returns the _preferred_ block replication factor instead of the _actual_ number of replicas. The current name is a little ambiguous. {{getPreferredBlockStorageNum}} is also consistent with {{getPreferredBlockSize}}
> # With the erasure coding feature, the name doesn't apply to striped blocks.
