Viewed 5455

Running an application in in client mode, the driver logs are printed with the below info messages, any idea on how to resolve this? Any spark configs to be updated? or missing?

[INFO ][dispatcher-event-loop-29][SparkRackResolver:54] Got an error when resolving hostNames. Falling back to /default-rack for all

The jobs runs fine, this msg is not in the executor logs.
