If I set the following property in Impala config for admission control and pool "default", in llama-site.xml:
<property> <name>llama.am.throttling.maximum.placed.reservations.root.default</name> <value>4</value></property>
Suppose I have 3 Impala nodes and all of them have the same configuration above.
Does that mean I can run up to 12 concurrent queries (4 in each impalad) in default pool or just 4 overall?
the property "llama.am.throttling.maximum.placed.reservations.root.*" places a limit on the total number of queries across the cluster. So in this case you can only run 4 overall
