Haohui Mai created HDFS-8227:
--------------------------------
Summary: BlockCollection should return Block instead of
BlockInfoContiguous in the interfaces
Key: HDFS-8227
URL: https://issues.apache.org/jira/browse/HDFS-8227
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Haohui Mai
Assignee: Haohui Mai
Currently the {{BlockCollection}} interface returns {{BlockInfoContiguous}}
objects in multiple calls.
In order to decouple block manager and the namespace, the interface should
return the {{Block}} instead of {{BlockInfoContiguous}} objects, where the
latter contain information like the locations of DN.
This jira proposes to clean up the interface and to return the {{Block}}
objects directly.
