> Global Dictionary store data on hdfs directly, and overwrite directly when
> data file updated. If the server crashed suddenly during writing file, the
> data file may be corrupt and can't be recovered.
> To resolve this problem, copy the data file into a tmp directory and copy
> back after the file is updated successfully.
> I'll post a patch later with this solution.
