Date Fri, 13 Mar 2015 23:08:38 GMT

    [ https://issues.apache.org/jira/browse/DRILL-2453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14361278#comment-14361278

Venki Korukanti commented on DRILL-2453:
----------------------------------------

[~cwestin] I don't think the issue you are seeing in your private branch is same as this one.
HBase test is failing with following error on your [branch|https://github.com/cwestin/incubator-drill/tree/interrupt].
Moreover the query failing is a simple select with no aggregation/join, so it shouldn't have
any PartitionSender. Looking at the place of failure, it is a new code added in your branch.
Could you please take a look at it and let me know.

One of the two will be used. Which one is undefined.
