What is the maximum number of executors that can be added in a coordinator?

[#1]

From the doc i can see below suggestion but i couldn't see the max number.

You might need 1 coordinator for every 50 executors.

Hi @yo_leo 

As per document, it is mentioned that you should have at most 50 executors per coordinator. Which is the recommended maximum value.

However this may vary as per the workload and complexity of the queries executed in Impala
