NoHostAvailableException when column family is unconfigured

[SusilPanda]

In this case when column family is unconfigured we should get the exception InvalidQueryException.
But I am getting NoHostAvailableException.

This exception should come in the getMappingSession method.
My query is why this exception is coming ?

Thanks in advance.

NoHostAvailableException thrown by datastax core driver. I don't handle it in my module.
But if you can consistently reproduce it, please post code sample here.
Otherwise it hard to guess what is going on

Hi,
The exception I am getting while fetching employee details using get method.
Example : I have an employee column family
CF : Employee
emp_id emp_name emp_address
1234 abc India

Now I run the below query :
Employee employee = mapper.get(employeeDto);

Exception scenario : My CF has been dropped when I run the above query. In this case I expect the exception will be InvalidQueryException, but NoHostAvailableException is thrown.

And this exception is not consistent , sometimes com.google.common.util.concurrent.UncheckedExecutionException - com.datastax.driver.core.exceptions.InvalidQueryExceptions is thrown.

Thanks
