> destination file
> -----------------------------------------------------------------------------------
>
> Key: HIVE-2407
> URL: https://issues.apache.org/jira/browse/HIVE-2407
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.7.1
> Reporter: Brian Muller
> Fix For: 0.8.0
>
>
> In the checkPaths method of Hive.java, a new destination filename will be
> chosen if the source filename already exists in the destination directory.
> This new filename follows the simple schema of adding _copy_N to the source
> filename (with increasing N until a non-existing filename is found).
> If the file has been LZO compressed it is imperative that the extension
> remain ".lzo" so that the LZO indexer can find it and create a corresponding
> index file. It would be much better to use a prefix of "copy_N_" or insert
> "_copy_N" somewhere else in the filename.
> Without this, Hive and LZO compression will not work when identical source
> filenames are inserted into Hive.
