> org.apache.kafka.streams.processor.internals.ProcessorStateManager: task
> [0_45] Failed to write offset checkpoint file to
> /tmp/kafka-streams/<application_id>
> {{ /0_45/.checkpoint: {}}}

> When state.dir is left at default configuration, there is a chance that
> certain files under the state directory are cleaned by OS since the default
> dir starts with /tmp/kafka-streams.
> [~mjsax] and I proposed to suggest user, through exception message, to change
> the location for state.dir .
