[jira] [Created] (HDFS-8655) Refactor accesses to INodeFile#blocks

Zhe Zhang created HDFS-8655:
-------------------------------

             Summary: Refactor accesses to INodeFile#blocks
                 Key: HDFS-8655
                 URL: https://issues.apache.org/jira/browse/HDFS-8655
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 2.7.0
            Reporter: Zhe Zhang
            Assignee: Zhe Zhang


When enabling INodeFile support for striped blocks (mainly in HDFS-7749), HDFS-7285 branch generalized the concept of blocks under an inode. Now {{INodeFile#blocks}} only contains contiguous blocks of an inode. This JIRA separates out code refactors for this purpose. Two main changes:
# Rename {{setBlocks}} to {{setContiguousBlocks}}
# Replace direct accesses to {{INodeFile#blocks}} to {{getBlocks}}

It also contains some code cleanups introduced in the branch.
