> When I run examples/hadoop_word_count. I find that ReducerToFilesystem is correct but when I use ReducerToCassandra, the program will call loadYaml().
> The reason is that the program catch a exception at line 196 of ColumnFamilyRecoderWriter.java. 
> Then it check why the exception occur, then it loadYaml to check if the disk is broken...
> However, the exception is NullPointerException. because the client is not initialized.
>  
> So we need a check to judge whether the client is null. 
> (
> The exception, original code and fixed code are in the attachments.
