DBD Deployment error

[Simo_Bond]

Hi,
in both the automatic and manual case, when I try to deploy a database design, after building phase has been done successfully, it fails.
Here I leave an extract (the output from "SELECT * FROM V_MONITOR.DEPLOY_STATUS;" ):

vmartdb=> SELECT * FROM V_MONITOR.DEPLOY_STATUS;

What should I do? I'm new to Vertica and I haven't found this error on other threads.
Thanks in advance to all,

The error is pretty self explanatory. Make sure that there are no other sessions requesting data (SELECT * FROM Test2;) otherwise exclude projection creation on this table.
