Jing Zhao created HDFS-8652:
-------------------------------
Summary: Track BlockInfo instead of Block in CorruptReplicasMap
Key: HDFS-8652
URL: https://issues.apache.org/jira/browse/HDFS-8652
Project: Hadoop HDFS
Issue Type: Improvement
Components: namenode
Reporter: Jing Zhao
Assignee: Jing Zhao
Currently {{CorruptReplicasMap}} uses {{Block}} as its key and records the list
of DataNodes with corrupted replicas. For Erasure Coding since a striped block
group contains multiple internal blocks with different block ID, we should use
{{BlockInfo}} as the key.
HDFS-8619 is the jira to fix this for EC. To ease merging we will use jira to
first make changes in trunk/branch-2.
