[jira] Commented: (HADOOP-5588) hadoop commands seem extremely slow in 0.20 branch

    [ https://issues.apache.org/jira/browse/HADOOP-5588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12690014#action_12690014 ] 

Hairong Kuang commented on HADOOP-5588:
---------------------------------------

Manual tests on dfs -ls/get etc. showed that the patch removed the additional listing call to the parent directory if the input path did not contain a glob.
