Subject [jira] [Commented] (TAJO-432) Add shuffle phase for column-partitioned table store
Date Thu, 26 Dec 2013 06:08:50 GMT

    [ https://issues.apache.org/jira/browse/TAJO-432?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13856772#comment-13856772

Hyunsik Choi commented on TAJO-432:

I think that It's not your mistake. Actually, we should have checked more various cases in
unit tests. 

A local cluster that I mentioned means a single hadoop cluster and a Tajo cluster running
on that cluster. It can be available with a very simple tajo-site.xml as follows. I expect
that you already setup a local cluster.




In addition, if you set a launch config in your IDE with two class paths ${TAJO_HOME}/conf
and ${HADOOP_HOME}/etc/hadoop, you can directly execute TajoMaster or TajoWorker in your IDE.
It will give more benefits for debugging.

> As we discussed in TAJO-283, column-partitioned store needs hash shuffle phase. The main
objective of this issue is to modify GlobalPlanner to do so.
