"...with a single integer value". From the example, it looks like you
meant, "...with a single integer column." I'm wondering what the column values

> Key: TRAFODION-2637
> URL: https://issues.apache.org/jira/browse/TRAFODION-2637
> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-general
> Affects Versions: 2.1-incubating
> Reporter: Hans Zeller
> Assignee: Hans Zeller
> Fix For: 2.2-incubating
>
>
> We have a set of built-in stored procedures that can be used to deploy
> libraries for UDRs to a Trafodion cluster. Some of these stored procedures
> rely on the pdsh command, which in turn relies on password-less ssh between
> the nodes of a cluster. Some installations, however, don't support
> password-less ssh. We therefore need to find another method to distribute the
> files.
