Zhe Zhang updated HDFS-8255:
----------------------------
Attachment: HDFS-8255.000.patch
> Rename getBlockReplication to getPreferredBlockStorageNum
> ---------------------------------------------------------
>
> Key: HDFS-8255
> URL: https://issues.apache.org/jira/browse/HDFS-8255
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: 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.
