Impala Concurrent Client Connections

Impala Concurrent Client Connections

New Contributor


I am new in Impala, and we always encounter an issue on Impala Active Client Connection getting exceeded. We first set it from 64 to 128, it gets resolved but after a few weeks we still get the error. My question is how can we detect the number of connections in real time aside from checking it in Active Frontend API Connections Chart? How to get the exact number of clients and queries it run which causes it to reach its max limit? How are connection being closed (i.e. are they closed once an impala query is completed or is there some other process), how can we monitor those open queries other than in queries tab?
