Zhe Zhang updated HDFS-8499:
----------------------------
Attachment: HDFS-8499.01.patch
Updating the patch to move {{addStorage}}, {{removeStorage}}, {{numNodes}},
{{replaceBlock}} to {{BlockInfoUC}} per above discussion.
I went through {{BlockInfoStripeUC}} in HDFS-7285 branch again. If we unify
{{replicas}} (or create some wrapper functions that work on both array and
list), then we only need to implement these 3 methods separately in
{{BlockInfoUCStriped}} and {{BlockInfoUCContiguous}}:
# {{setExpectedLocations}} -- the striped version needs to create block IDs for
internal blocks
# {{getTruncateBlock}} and {{setTruncateBlock}} -- truncate not supported under
striping yet
For now these 3 methods are left in {{BlockInfoUC}} to simplify the patch.
> Merge BlockInfoUnderConstruction into trunk
