Zhe Zhang updated HDFS-8655:
----------------------------
Attachment: HDFS-8655.01.patch
Updating patch to address comments from Haohui and Jing.
It also includes more consolidation so that {{blocks}} is only accessed by a
getter and a setter now. Moreover, {{setBlocks}}) is changed to private because
the only external use can be converted to a safer {{clearBlocks}} call.
> Refactor accesses to INodeFile#blocks

> 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.
