> Quoting stack trace from KAFKA-5998 :
> {code}
> WARN [2018-08-22 03:17:03,745] 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: {}}}
> {{ ! java.nio.file.NoSuchFileException: /tmp/kafka-streams/<application_id>/0_45/.checkpoint.tmp}}
> {{ ! at sun.nio.fs.UnixException.translateToIOException(UnixException.java:86)}}
> {{ ! at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:102)}}
> {code}
> 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 .
