push a query on a materialized table runs forever

[Baliram Maurya]

Hi There, I am running a push a query on a materialized table to get all the records and it's running forever.  Here is source code.  

String pullQuerySql = "select * from cn2_materialized where fromtype='cn';";        

 try {          

   return client.executeQuery(pullQuerySql).get();         }

 catch (ExecutionException | InterruptedException e) 

    {             throw new RuntimeException("Failed to get latest readings", e);  

       }
