> dfs -get should remove existing crc file if -crc is not specified

> Key: HADOOP-866
> URL: https://issues.apache.org/jira/browse/HADOOP-866
> Project: Hadoop
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.10.0
> Environment: All
> Reporter: Milind Bhandarkar
> Assigned To: Milind Bhandarkar
> Fix For: 0.11.0

>
> 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.
