Description

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] [-start] [-length] <src> ... <localdst>
