hadoop dfs -cp foo/bar/bad-file mumble/new-file copies a file with a bad
checksum
---------------------------------------------------------------------------------
Key: HADOOP-518
URL: http://issues.apache.org/jira/browse/HADOOP-518
Project: Hadoop
Issue Type: Bug
Components: dfs
Environment: red hat
Reporter: Dick King
I have a file that reliably generates a checksum error when it's read, whether
by a map/reduce job as input or by a "dfs -get" command.
However...
if I do a "dfs -cp" from the file with the bad checksum the copy can be read in
its entirety without a checksum error.
I would consider it reasonable for the command to fail, or for the new file to
be created but to also have a checksum error in the same place, but this
behavior is unsettling.
