Jonathan Eagles commented on HDFS-2777:
---------------------------------------
Seems like the temp file use for the target is created using the
CheckSumFileSystem(via RawLocalFileSystem) which unconditionally creates a crc
file at the destination.
CommandWithDestination.java (copyStreamToTarget)
FSDataOutputStream out = target.fs.getLocal().create(tempFile.path, true);
Not sure if this is a systemic problem of the RawLocalFileSystem or not.
> When copying a file out of HDFS, modifying it, and uploading it back into
> HDFS, the put fails due to a CRC mismatch

> Performing an hdfs -get on a file, modifying the file, and using hdfs -put to
> place the file back into HDFS results in a checksum error. It seems that the
> problem is a .crc file being generated locally from the -get command even
> though the -crc option was NOT specified.
