Subject [jira] [Commented] (HIVE-4577) hive CLI can't handle hadoop dfs command with space and quotes.
Date Mon, 20 May 2013 06:39:16 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13661811#comment-13661811

Bing Li commented on HIVE-4577:
-------------------------------

The root cause is in DfsProcessor class.
Hive parses command via a simple split("\\s+"), which won't handle the space between quotes
or ignore special characters ("/') in the path.

> As design, hive could support hadoop dfs command in hive shell, like 
> hive> dfs -mkdir /user/biadmin/mydir;
> but has different behavior with hadoop if the path contains space and quotes
> hive> dfs -mkdir "hello"; 
> drwxr-xr-x   - biadmin supergroup          0 2013-04-23 09:40 /user/biadmin/"hello"
> hive> dfs -mkdir 'world';
> drwxr-xr-x   - biadmin supergroup          0 2013-04-23 09:43 /user/biadmin/'world'
> hive> dfs -mkdir "bei jing";
> drwxr-xr-x   - biadmin supergroup          0 2013-04-23 09:44 /user/biadmin/"bei
> drwxr-xr-x   - biadmin supergroup          0 2013-04-23 09:44 /user/biadmin/jing"
