Zhe Zhang updated HDFS-8499:
----------------------------
Attachment: HDFS-8499.00.patch
The patch does the following:
# Renames {{BlockInfoContiguousUnderConstruction}} to
{{BlockInfoUnderConstruction}} to redirect all UC usages to the new class
# Converts {{BlockInfoUnderConstruction}} to an abstract class
# Creates {{BlockInfoUnderConstructionContiguous}} (note the name is changed to
reflect that it's a subclass of {{BIUC}} instead of {{BIContiguous}} now). It
implements the 4 abstract methods from {{BlockInfo}} by explicitly converting
itself to a {{BIContiguous}} first.
Uploading the patch to trigger Jenkins and gather some feedback on the overall
direction. I'm working on a rev to address down-casting from {{BI}} to {{BIUC}}
> Merge BlockInfoUnderConstruction into trunk
