             Summary: EC: Block gets marked as CORRUPT in case of failover and 
pipeline recovery
                 Key: HDFS-15170
                 URL: https://issues.apache.org/jira/browse/HDFS-15170
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Ayush Saxena
            Assignee: Ayush Saxena

Steps to Repro :
1. Start writing a EC file.
2. After more than one stripe has been written, stop one datanode.
3. Post pipeline recovery, keep on writing the data.
4.Close the file.
5. transition the namenode to standby and back to active.
6. Turn on the shutdown datanode in step 2

The BR from datanode 2 will make the block corrupt and during invalidate block 
won't remove it, since post failover the blocks would be on stale storage.
