Subject [jira] Commented: (HADOOP-738) dfs get or copyToLocal should not copy crc file
Date Wed, 22 Nov 2006 19:29:04 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-738?page=comments#action_12452029 ] 
            
Konstantin Shvachko commented on HADOOP-738:
--------------------------------------------

We plan to remove crc files as separate entities replacing them by
per block crcs on data-nodes. Do we still want to support crc files
just for local fs after that? If not then Milinds solution seems right.

> Currently, when we -get or -copyToLocal a directory from DFS, all the files including
crc files are also copied. When we -put or -copyFromLocal again, since the crc files already
exist on DFS, this put fails. The solution is not to copy checksum files when copying to local.
Patch is forthcoming.
