Subject [jira] [Created] (HDFS-8227) BlockCollection should return Block instead of BlockInfoContiguous in the interfaces
Date Thu, 23 Apr 2015 05:22:38 GMT
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.
