     [ http://issues.apache.org/jira/browse/HADOOP-769?page=all ]

Sanjay Dahiya resolved HADOOP-769.

    Resolution: Later

This problem is not appearing anymore, I presume it was something to do with file closing.

Marking resolved.

>                 URL: http://issues.apache.org/jira/browse/HADOOP-769
>             Project: Hadoop

>          Components: dfs
>            Reporter: Sanjay Dahiya
> I am not sure whats going wrong here but after a file rename operation on a bunch of
files, I am losing crc files in the destination directory. It causes exceptions when doing
dfs -get or any other operation on the file. 
> I added some prints and it seems renameRaw() is called on checksum file but its not created
in target path. There are no errors in namenode logs also. 
> I will debug this further and more details if i find any. 
> FileSystem.java:386 
> -------
>       Path checkFile = getChecksumFile(src);
>         if (exists(checkFile)) { //try to rename checksum
>           if(isDirectory(dst)) {
>             renameRaw(checkFile, dst);
>           } else {
>             renameRaw(checkFile, getChecksumFile(dst));                    <=== This
is executed.
