> 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.
