[jira] [Created] (HAWQ-1120) Optimize hawqregister performance

hongwu created HAWQ-1120:
----------------------------

             Summary: Optimize hawqregister performance
                 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: Lei Chang
             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.

In check_sizes_valid, we could bind du operation together to optimize. For the other two functions, there is nothing to do with it.
