-------------------------------
Summary: 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
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.
# With the erasure coding feature, the name doesn't apply to striped blocks.
