             Summary: Erasure Coding: handle missing internal block locations 
in DFSStripedInputStream
                 Key: HDFS-8669
                 URL: https://issues.apache.org/jira/browse/HDFS-8669
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Jing Zhao
            Assignee: Jing Zhao


Currently DFSStripedInputStream assumes we always have complete internal block 
location information, i.e., we can always get all the DataNodes for a striped 
block group. We should add functionality to handle missing block locations.
