Subject [jira] Commented: (MAPREDUCE-1341) Sqoop should have an option to create hive tables and skip the table import step
Date Fri, 05 Feb 2010 00:44:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1341?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12829888#action_12829888
] 

Aaron Kimball commented on MAPREDUCE-1341:
------------------------------------------

Patch looks pretty good -- just a couple of small issues:

Sqoop.java -- Please use spaces not tabs.

SqoopOptions.doCreateTableOnly(), doOverwriteTable(): maybe call these doCreateHiveTableOnly
/ doOverwriteHiveTable? There are a lot of "tables" floating around... the field names include
"Hive" which is good. Getters should reflect that too.

Please add --hive-create-only, --hive-overwrite to the documentation in src/contrib/sqoop/doc/Sqoop-manpage.txt
and hive.txt. These files are in ASCIIDOC format -- see http://powerman.name/doc/asciidoc
and http://www.methods.co.nz/asciidoc/userguide.html if you need syntax help here.

> In case the client only needs to create tables in hive, it would be helpful if Sqoop
had an optional parameter:
> --hive-create-only
> which would omit the time consuming table import step, generate hive create table statements
and run them.
> If this feature seems useful, I can generate the patch. I have modified the Sqoop code
and built it on my development machine, and it seems to be working well.
