Cassandra Engine installed but not working

Hello,

I am working on using HeidiSql to create a table using Cassandra Engine.
I can see Cassandra engine available to select in the drop down box but when i select it and try to create a table it gives me an error -:
"Unable to Connect to foreign Data source, Connect() failed, connection refused"

Other thing i have noticed is that when i try to create the same table thru the script i get the same error but i notice something unusual

create table t2 (pk varchar(36) primary key,
data1 varchar(60),
data2 bigint
) engine=cassandra
keyspace='mariadbtest'
thrift_host='127.0.0.1'
column_family='cf1';

in the script, the word "Cassandra" should be turned into Red font as it turns with other available engines.

Cassandra is installed fine as an engine in this heidisql installation of mine.

is there something missing that i need to do to activate the Cassandra Engine?

I would appreciate anyones help here.

Thank you
