query tab in the kylin url

[Shilpa S]

I have run the samples.sh after downloading kylin on my CDH 5.4 cluster. My cube is in ready state, but when I go to the query tab none of the tables are listed.

And when I run "select * from kylin_sales", it shows kylin_sales table not found. I tried using the 'DEFAULT'.Kylin_sales, but that started giving the XML error. 

I would like to know how do I get the data from the cube, if the query window is not working.
