> In a secure cluster, I noticed that every time I run an Impala query, it issues new service tickets for every tablet server on the coordinator node. It seems like it is creating a new connection to each tablet server, despite not actually needing to access any data. This is probably a big part of why planning is slow for larger clusters.
