Guo Ruijing created HDFS-6818:
---------------------------------

             Summary: Enhance hdfs get to copy file with length
                 Key: HDFS-6818
                 URL: https://issues.apache.org/jira/browse/HDFS-6818
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Guo Ruijing


Use Case: if HDFS file is corrupted, some tool can be used to copy out good part of corrupted file. We may enhance "hdfs -get" to copy out good part.

Existing:
hadoop fs [generic options] -get [-p] [-ignoreCrc] [-crc] <src> ... <localdst>

Proposal:

hadoop fs [generic options] -get [-p] [-ignoreCrc] [-crc] [-length] <src> ... <localdst>
