> 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>
