Zhe Zhang updated HDFS-7969:
----------------------------
Attachment: HDFS-7969-000.patch
Main changes introduced by the patch:
# A {{BlockInfoUC}} interface to avoid duplicating code on processing UC block
info
# Filled {{BlockInfoStripedUnderConstruction#initializeBlockRecovery}} with the
same algorithm from {{BlockInfoContiguousUnderConstruction}}. I looked at the
algorithm of selecting primary recovery replica and don't see a clear need to
change it for striped blocks. [~jingzhao] Do you have any idea on this? I
considered avoiding parity replicas but there's no clear reason for that.
> Erasure coding: lease recovery for striped block groups
