Subject [jira] Commented: (HIVE-602) INSERT LOCAL PIPE '/path/to/program' would be lovely
Date Thu, 02 Jul 2009 09:02:47 GMT

    [ https://issues.apache.org/jira/browse/HIVE-602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12726392#action_12726392

Zheng Shao commented on HIVE-602:

Can you try: hive -S -e "SELECT ..." > filename?
I think this is what you want.

> INSERT OVERWRITE LOCAL DIRECTORY is great at what it does, but the output is never _instantly_
useful. Why? Because it is a whole bunch of gzipped files.
> It would be lovely if I could tell Hive what it should do with its output when inserting
into a local directory. For example, to automatically pipe its output through something. Really,
I want to
> gunzip -c *.gz | perl -p -e 's/\cA/\t/g' > filename
> ...but I would settle for piping every reducer's output through gunzip -c | perl -p -e
's/\cA/\t/g' and then having Hive save the result to whatever it would have used for a filename
but without the .gz.
