> ---------------------------------
>
> Key: HAWQ-1120
> URL: https://issues.apache.org/jira/browse/HAWQ-1120
> Project: Apache HAWQ
> Issue Type: Sub-task
> Components: Command Line Tools
> Reporter: hongwu
> Assignee: hongwu
> Fix For: 2.0.1.0-incubating
>
>
> move_files_in_hdfs, check_sizes_valid and check_file_not_folder take 30%
> execute time of hawqregister since invoking hadoop shell command has 1-2s
> lantency each time.
> In check_sizes_valid, we could bind "du" operation together to optimize. For
> the other two functions, there is nothing to do.
