Subject [jira] Commented: (PIG-891) Fixing dfs statement for Pig
Date Fri, 11 Sep 2009 01:43:57 GMT

    [ https://issues.apache.org/jira/browse/PIG-891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12753944#action_12753944
] 

Daniel Dai commented on PIG-891:
--------------------------------

+1. Patch is concise and clear. 

For the syntax, I need opinion from other developers / users:
1. After this patch, shall we remove existing hadoop file system commands since they are duplicate
with the new one
2. Shall we allow both fs/dfs to indicate a dfs command, just like hadoop does?

> Several hadoop dfs commands are not support or restrictive on current Pig. We need to
fix that. These include:
> 1. Several commands do not supported: lsr, dus, count, rmr, expunge, put, moveFromLocal,
get, getmerge, text, moveToLocal, mkdir, touchz, test, stat, tail, chmod, chown, chgrp. A
reference for these command can be found in http://hadoop.apache.org/common/docs/current/hdfs_shell.html
> 2. All existing dfs commands do not support globing.
> 3. Pig should provide a programmatic way to perform dfs commands. Several of them exist
in PigServer, but not all of them.
