> When we added -crc option to dfs -get (aka dfs -copyToLocal) the absence of this command-line
option implies not copying the crc file associated with hdfs file. However, if the checksum
file already exists, it will not correspond with the newly copied data file, and opening it
would cause checksum failure. The solution is to remove any existing crc file corresponding
to the data file if -crc option is not given for -get. Patch forthcoming.
