Subject [jira] [Updated] (HDFS-8482) Merge BlockInfo from HDFS-7285 branch to trunk
Date Wed, 27 May 2015 19:06:24 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8482?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Zhe Zhang updated HDFS-8482:

Initial patch which simply renames {{BlockInfoContiguous}} back to {{BlockInfo}}. 

The next step is more complex: we need to:
# Change {{BlockInfo}} to abstract class
# Create new {{BlockInfoContiguous}} to implement {{BlockInfo}}
# Clearly separate where to use the abstract class versus the subclass

> Per offline discussion with [~andrew.wang], for easier and cleaner reviewing, we should
probably shrink the size of the consolidated HDFS-7285 patch by merging some mechanical changes
that are unrelated to EC-specific logic to trunk first. Those include renames, refactors for
subclassing purpose, and so forth. This JIRA specifically aims to merge {{BlockInfo}} back
into trunk.
