impala dedicated co-ordinator and executor

[ Edited ]

Hi,

We have a 32 node impala cluster where each node is both an executor and a coordinator. We wanted to dedicate 6 nodes as co-ordinators and the rest as executors.

We created two config groups and set is_executor=false for coordinators and is_coordinator=false for executors and we restarted the impala service. 

We deleted a table and tried to recreate it we got an error saying the table already exist.

We would like to know how to refresh the metadata on all the nodes.
