Setting config parameter does not work

On the database side you can query the tuple_mover_operations system table. In the example below we can see it's set to 300 secs (5 mins). And querying the tuple_mover_operations table we can see that the moveouts happened roughly 300 secs apart. So if you set the config param you can check it with the get function, then you can confirm it took affect with the system table query.

I checked this in Vertica 9.2 and MC reflected the changed value in the settings tab.

dbadmin=> select get_config_parameter('moveoutinterval');

get_config_parameter

300

dbadmin=> select operation_start_timestamp,node_name,operation_name,table_name,is_executing from tuple_mover_operations where operation_name='Moveout' and operation_start_timestamp > 'Mar 01, 2019 12:00:00' order by operation_start_timestamp desc limit 12;
operation_start_timestamp | node_name | operation_name | table_name | is_executing
-------------------------------+------------------+----------------+------------+--------------
2019-03-12 08:44:34.294277-04 | v_vmart_node0001 | Moveout | invfact | f
2019-03-12 08:44:34.024571-04 | v_vmart_node0001 | Moveout | invfact | f
2019-03-12 08:39:34.285578-04 | v_vmart_node0001 | Moveout | invfact | f
2019-03-12 08:39:34.008701-04 | v_vmart_node0001 | Moveout | invfact | f

I hope it helps.
