    Description

      When doing a transferTo (aka sendfile operation) from the DataNode to a client, we may hit an I/O error from the disk. If we believe this is the case, we should be able to tell the block scanner to rescan that block soon. The feature was originally implemented in HDFS-7548 but was removed by HDFS-7430. We should re-add it.
